Neglecting the change of kinetic and potential energies and assuming that the cross-sectional area of the inlet and outlet to be the same, determine: a) the mass flow rate (kg/s) m b) the gas temperature at outlet (°C) c) the ratio of outlet to inlet velocities d) the volumetric flow rate at outlet (m³/s). Take the value of cp and k of the gas to be 1.15kJ/kg.K and 1.3 respectively. Cp = 1.15kJ/kg, k K 1-3
