A vessel containing air at a temperature of 22°C is fitted with a convergent nozzle of tip diameter 30 mm. Assuming adiabatic flow, determine the mass flow rate of air through the nozzle to the atmosphere when the pressure in the tank is (i) 150 kPa (abs) and (ii) 300 kPa. Take R = 287 J/kg K, γ = 1 4. and atmospheric pressure as 101.325 kPa.
