Stoichiometry One kg of saturated steam at 100°C and 1.01325 bar is contained in a rigid walled vessel. It lias a volume of 1.673 m³. It cools to 98°C ; the saturation pressure is 0.943 bar ; one kg of water vapour under these conditions has a volume of 1.789 m³. The latent heat of condensation (kJ/kg⁻¹ ) under these conditions is 2263 40732 540 2676 2263 40732 540 2676 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Heat capacity of air can be approximately expressed as, Cp = 26.693 + 7.365 x10⁻³ T, where, Cp is in J/mole.K and T is in K.
