Ideal-gas enthalpy change

Calculates heat from mass, cp, and temperature change at constant pressure.

Calculates ideal-gas internal energy change from mass, cv, and temperature change.

Calculates ideal-gas absolute temperature from pressure, volume, mass, and specific gas constant.

Calculates temperature change from heat energy, mass, and specific heat.

Calculates ideal-gas polytropic process work for n not equal to 1.

Calculates an ideal Rankine-cycle balance from manually entered enthalpies h1–h4.
