A gas gun fires gas from a nuzzle of area 160mm^2 at a speed of 150m/s tye density of the gas is 0.800kg/m^3 .the mass of the astronaut including her space suit is 130kg. Calculate i) the mass of gas leaving the gun per second

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
