Learning objectives of the subject Total learning time: h Hours large group: thermodynamics tells us nothing about the mechanisms of energy transfer, rates of change, and time associated with a system changing from one equilibrium state to another, it is still the lynch-pin that allow us to answer these questions.

In broad terms, thermodynamics deals with the transfer of energy from one place to another and from one form to another. Any materialthat has a temperature above absolute zero gives off some radiant energy. Specifically, thermodynamics focuses largely on how a heat transfer is related to various energy changes within a physical system undergoing a thermodynamic process. When there are simultaneous energy and mass flows, heat flow must be considered at a yunus a cengel PDF download.

Both deals with heat and energy then, one might ask, what is the real difference between the two subjects? Based Heat exists only as it crosses the boundary of a system and the direction of heat transfer is from higher temperature to lower temperature.

Most pressure gauges give readings which are the difference between the pressure of interest and the pressure of the surrounding atmosphere. These readings are known as gauge pressures, and can be converted to absolute pressures by addition of the barometric pressure.

Absolute pressures must be used in thermodynamic calculations. Introduction 8 1. When integrated, this equation yields the work of a finite process. By convention, work is regarded as positive when the displacement is in the same direction as the applied force and negative when they are in opposite directions.

The work which accompanies a change in volume of a fluid is often encountered in thermodynamics. A common example is the compression or expansion of a fluid in a cylinder resulting from the movement of a piston. The force exerted by the piston on the fluid is equal to the product of the piston area and the pressure of the fluid. The displacement of the piston is equal to the total volume change of the fluid divided by the area of the piston.

Equation 1. When the piston moves into the cylinder so as to compress the fluid, the applied force and its displacement are in the same direction; the work is therefore positive. The minus sign is required because the volume change is negative. For an expansion process, the applied force 9 1. Energy and its displacement are in opposite directions. The volume change in this case is positive, and the minus sign is required to make the work negative. This path relates the pressure at any point of the process to the volume.

The work required is given by Eq. The SI unit of work is the newton-meter or joule, symbol J. In the metric engineering system the unit often used is the meter-kilogram force m kgf. Figure 1. V path f 1. The germ of this principle as it applies to mechanics was implicit in the work of Galileo and Isaac Newton Indeed, it follows directly from Newton's second law of motion once work is defined as the product of force and displacement.

Kinetic Energy When a body of mass m, acted upon by a force F, is displaced a distance dl during a differential interval of time d t , the work done is given by Eq.

In combination with Newton's second law this equation becomes: By definition the acceleration is a - d u l d t , where u is the velocity of the body.

Thus, by definition, EK 1 2 -- -mu 2 1. Conversely, if a moving body is decelerated by the action of a resisting force, the work done by the body is equal to its change in kinetic energy. In accord with Eq.

Potential Energy If a body of mass m is raised from an initial elevation zl to a final elevation z2, an upward force at least equal to the weight of the body must be exerted on it, and this force must move through the distance 22 - zl. Since the weight of the body is the force of gravity on it, the minimum force required is given by Newton's law: where g is the local acceleration of gravity.

Energy 11 We see from Eq. Conversely, if the body is lowered against a resisting force equal to its weight, the work done by the body is equal to the change in the quantity mzg. In each case the work performed can be recovered by carrying out the reverse process and returning the body to its initial condition. This observation leads naturally to the thought that, if the work done on a body in accelerating it or in elevating it can be subsequently recovered, then the body by virtue of its velocity or elevation contains the ability or capacity to do the work.

This concept proved so useful in rigid-body mechanics that the capacity of a body for doing work was given the name energy, a word derived from the Greek and meaning "in work. In the metric engineering system, potential energy is expressed as mzglg,. Energy Conservation In any examination of physical processes, an attempt is made to find or to define quantities which remain constant regardless of the changes which occur.

One such quantity, early recognized in the development of mechanics, is mass. The great utility of the law of conservation of mass suggests that further conservation principles could be of comparable value. Thus the development of the concept of energy logically led to the principle of its conservation in mechanical processes.

If a body is given energy when it is elevated, then the body conserves or retains this energy until it performs the work of which it is capable. An elevated body, allowed his term was first proposed in by the Scottish engineer William Rankine Introduction to fall freely, gains in kinetic energy what it loses in potential energy so that its capacity for doing work remains unchanged. For a freely falling body this means that: The validity of this equation has been confirmed by countless experiments.

Success in application to freely falling bodies led to the generalization of the principle of energy conservation to apply to all purely mechanical processes. Ample experimental evidence to justify this generalization was readily obtained. Other forms of mechanical energy besides lunetic and gravitational potential energy are possible.

The most obvious is potential energy of configuration. When a spring is compressed, workis done by an external force. Since the spring can later perform this work against a resisting force, the spring possesses capacity for doing work. This is potential energy of configuration.

Energy of the same form exists in a stretched rubber band or in a bar of metal deformed in the elastic region. The generality of the principle of conservation of energy in mechanics is increased if we look upon work itself as a form of energy.

This is clearly permissible, because both kinetic- and potential-energy changes are equal to the work done in producing them [Eqs. However, work is energy in transit and is never regarded as residing in a body. When work is done and does not appear simultaneously as work elsewhere, it is converted into another form of energy. The body or assemblage on which attention is focused is called the system. All else is called the surroundings. When work is done, it is done by the surroundings on the system, or vice versa, and energy is transferred from the surroundings to the system, or the reverse.

It is only during this transfer that the form of energy known as work exists.

Solution Manual-Chemical Engineering Thermodynamics - Smith Van Ness

In contrast, kinetic and potential energy reside with the system. Their values, however, are measured with reference to the surroundings; i. Changes in kinetic and potential energy do not depend on these reference conditions, provided they are fixed. Introduction During the period of development of the law of conservation of mechanical energy, heat was not generally recognized as a form of energy, but was considered an indestructible fluid called caloric.

This concept was firmly entrenched, and for many years no connection was made between heat resulting from friction and the established forms of energy. The law of conservationof energy was therefore limited in application to frictionless mechanical processes. No such limitation is necessary; heat like work is now regarded as energy in transit, a concept that gained acceptance during the years following , largely on account of the classic experiments of J.

These experiments are considered in detail in Chap. A reasonable view is that something is transferred from the hot object to the cold one, and we call that something heat Q. This leads to the concept of temperature as the driving force for the transfer of energy as heat. More precisely, the rate of heat transfer from one body to another is proportional to the temperature difference between the two bodies; when there is no temperature difference, there is no net transfer of heat.

In the thermodynamic sense, heat is never regarded as being stored within a body. Like work, it exists only as energy in transit from one body to another, or between a system and its surroundings. When energy in the form of heat is added to a body, it is stored not as heat but as kinetic and potential energy of the atoms and molecules making up the body.

Problems 15 In spite of the transient nature of heat, it is often viewed in relation to its effect on the body from which it is transferred. As a matter of fact, until about , the definitions of units of heat were based on the temperature changes of a unit mass of water.
