Most of the scientific and engineering problems may be solved by considering temperature and pressure as independent variables, but in some cases we need to consider other variables as independent parameters like the pressure-enthalpy chart, which is of extreme importance for electricity production ...

In a certain mountain range, water boils at 92 degrees Celsius. What is the atmospheric pressure (in mmHg) under these conditions? The enthalpy of vaporization of water at 100 degrees Celsius is 40.7 kJ/mol. Why is the heat of vaporization of ...
Temperature and pressure of water at various state is given in the problem and we have to determine the phase, specific volume and specific enthalpy. Quality of liquid-vapor mixture is defined as the ratio of the mass of vapor to the total mass of the liquid-vapor mixture. The value of ...

U→Iwhere h, p, kc, ∇T represent the enthalpy, pressure, thermal conductivity, and temperature gradient, respectively. In some analyses, the fluid flow in the OWC system is assumed to be incompressible, meaning, ρ = constant. This assumption allows the NSE to be solved numerically using...
H(T) and S(T,P) are the reaction enthalpy and entropy, respectively, which are thermophysical properties with tabulated values retrieved in EES. The kinetic overvoltage, Ukin, is the sum of the activation barrier on the anode (ηO2) and the cathode (ηH2) which can be described by the...
conductive heat flow takes place towards the cold side, while within the free space of the pores, energy is carried by the volatile molecules quantified by the enthalpy of vaporization. Lastly, a convective mechanism takes place from the permeate surface of the membrane to the bulk of the fluid...
Why is enthalpy of vaporization greater than fusion? 1. Why must heat energy be supplied to melt ice? 2. After all, does the temperature not change? Explain how water's entropy can decrease when it freezes without violating the second...
For practical purposes the process of adding saturated steam at atmospheric pressure approximates the horizontal temperature line. The water vapor added can be calculated using (1). The enthalpy added can be estimated by using the Mollier diagram or a psyhrometric chart. Example - Humidifying Air...
