The formula is: Thermal loss = Cp x 0.8 ( 38 – IT ) x Q x P / 60 + LV. Universal Ideal Gas Equation: · P is the pressure of the gas · V is the volume of the gas · n is the amount of gas ie the number of moles present in the gas · R is the where the formula weight (FW) is in g/mol, and the standard molar volume is 22.4 L/mol.
