Q. A gas is heated in a duct as it flows over a resistance heater. Consider a 101 kW electric heating system. The gas enters the heating section of the duct at 100 kPa and 27 \u00baC with a volume flow rate of 15 m3<\/sup>\/s. If heat is lost from the gas in the duct to the surroundings at a rate of 51 kW, the exit temperature of the gas is (Assume constant pressure, ideal gas, negligible change in kinetic and potential energies and constant specific heat; C<\/em>p = 1 kJ\/kg\u00b7K; R <\/em>= 0.5 kJ\/kg\u00b7K.)<\/p>\n\n\n\n
