It features over new homework problems which further enhance the extensive and diverse homework problem sets, and physical intuition to help students develop a sense of the underlying physical mechanisms and a mastery of solving practical problems that an engineer is likely to face in the real world. The title includes a free Student Resources DVD containing Limited Academic Version of EES Engineering Equation Solver software with scripted solutions to selected text problems, Physical experiments in thermodynamics with videos and complete write-ups of the experiments, as well as actual data, and an Interactive Thermodynamics Tutorial to reinforce student learning of thermodynamics concepts.

Boles Thermodynamics: Those that are independent of the mass of a system, such as temperature, pressure, and density. Those whose values depend on the size— or extent—of the system. Extensive Criterion to differentiate intensive properties per unit mass.
Yet it is very convenient to disregard the atomic nature of a substance and view it as a continuous, homogeneous matter with no holes, that is, a continuum.
Specific weight: The weight of a unit volume of a substance. Density is mass per unit volume; specific volume is volume per unit mass. A state of balance. If the temperature is the same throughout the entire system. A system at two different states.
If there is no change in pressure at any point of the system with time. If a system involves two phases and when the mass of each phase reaches an equilibrium level and stays there. If the chemical composition of a system does not change with time, that is, no chemical reactions occur. A closed system reaching thermal equilibrium. If a system involves The state of nitrogen is no electrical, magnetic, fixed by two independent, gravitational, motion, and intensive properties.
Any change that a system undergoes from one equilibrium state to another. The series of states through which a system passes during a process. To describe a process completely, one should specify the initial and final states, as well as the path it follows, and the interactions with the surroundings. Quasistatic or quasi-equilibrium process: When a process proceeds in such a manner that the system remains infinitesimally close to an equilibrium state at all times.
A process during which the temperature T remains constant. A process during which the pressure P remains constant.
A The P-V diagram of a compression process during which the specific volume v remains constant. A process during which the initial and final states are identical. The opposite of steady is unsteady, or transient. A position but not process during which a fluid with time. If two bodies are in thermal equilibrium with a third body, they are also in thermal equilibrium with each other.
Two bodies reaching thermal equilibrium after being brought into contact in an isolated enclosure. A temperature scale that is independent of the properties of any substance. The temperatures on this scale are measured using a A constant-volume gas thermometer would constant-volume gas thermometer. Comparison of temperature scales. Comparison of magnitudes of various temperature units. A normal force exerted by a fluid per unit area.
Some basic pressure 23 gages. The actual pressure at a given position. It is measured relative to absolute vacuum i. The difference between the absolute pressure and the local atmospheric pressure. Most pressure-measuring devices are calibrated to read zero in the atmosphere, and so they indicate gage pressure. Pressures below atmospheric pressure.
Throughout this text, the pressure P will denote absolute pressure unless specified otherwise. The pressure of a fluid at rest Free-body diagram of a rectangular increases with depth as a fluid element in equilibrium. Pressure in a liquid at rest increases linearly with distance from the free surface.
The pressure is the same at all points on a horizontal plane in a given fluid regardless of geometry, provided that the points are interconnected by the same fluid. The pressure applied to a confined fluid increases the pressure throughout by the same amount. A manometer contains one or more fluids such as mercury, water, alcohol, or oil. Measuring the pressure drop across a flow section or a flow device by a differential manometer. The basic manometer. Consists of a hollow metal tube bent like a hook whose end is closed and connected to a dial indicator needle.
Use various techniques to convert the pressure effect to an electrical effect such as a change in voltage, resistance, or capacitance. Work by having a diaphragm deflect between two chambers open to the pressure inputs. Also called solid- state pressure transducers, work on the principle that an electric potential is generated in a crystalline substance when it is subjected to mechanical pressure. Various types of Bourdon tubes used 29 to measure pressure.
The length or the cross-sectional area of the tube has no effect on the height of the fluid column of a barometer, provided that the tube diameter is large enough to avoid surface tension capillary effects.

Force units, for example, can be expressed as They can also be expressed more conveniently as unity conversion ratios as To be dimensionally homogeneous, all the Unity conversion ratios are identically equal to 1 and terms in an equation are unitless, and thus such ratios or their inverses must have the same unit.
