H = U + pV In many thermodynamic analyses, it is convenient to useenthalpyinstead of internal energy, especially in thefirst law of thermodynamics. In engineering, both important thermodynamic cycles (Brayton and Rankine cycle) are based ontwo isobaric processes. Therefore the study of this proces...
IB PhysicsThermodynamic ProcessesThe study of thermodynamics resulted from the desire during the industrial revolution to understand and improve the performance of heatengines such as the steam engine and later, the internal combustion engine.This section contains many references to heat and temperature ...
A representation of an expansion process on a P-V diagram. A few processes are of special interest in thermodynamics. For example, a process that takes place with the temperature of the system held fixed is called an isothermal process, and the ideal gas equation of state becomes PV=nRT=...

In order to motivate the necessity of a consistent consideration of uncertainties, this work presents an investigation of the effect of different uncertainty considerations in parameter regression on a deterministic process design of distillation processes. Therefore, different objective functions for the par...
An ideal non-atomic gas is taken round the cycle ABCDA in the P-V diagram where the coordinates of the points are : A(P1,V1),B(2P1,V1),C(2P1,2V1)andD(P1,2V1)The work done during the cycle is AP1V1 B2P1V1 C1/2P1V1 ...
In a matter of speaking, this was due to the lack of the concepts of volume and pressure for a black hole in the original derivation, based on accretion processes. Several works have studied this issue in the last 20 years [6– 9]. To address this problem let us consider the first ...
9 Conclusion A two-phase flow boiling model for quenching processes has been developed in the 3D domain and sufficiently vali- dated, considering the hydrodynamic and thermodynamic aspects as well as for different plate materials and initial temperatures. A detailed investigation has been carried ...
Methods Density and other derived thermodynamic properties using GERG-2008 Equation of State (EoS). To efficiently design and operate the technical processes involved in gas-based energy industries, precise rep- resentation of the thermodynamic properties using an accurate EoS is essential. Here,...
Efficiency formulations are explained for most important engineered devices such as turbines, compressors, pumps, chemical reactors, and psychrometric processes. Study Problems 1.1. Explain the difference between flow work and boundary work. 1.2. Explain the difference between closed and open thermodynamic...
