I need some help in this problem, all efforts will be appreciated;(adsbygoogle = window.adsbygoogle || []).push({});

a gas flows into a rigid tank initially evacuated.Assume that the inflow velocity is uniform at 2m/s.The tube inlet diameter is 10cm with the volume of the tank equal to 2000litres. The pressure and temperature in the inlet line are maintained constant at 400 kPa and 330 K; respectively. The gas can be assumed to obey the prefect gas law P=ñρRT, with R=300 J/kg.K. Assume the tank to be non-insulated so that the temperature of the gas remains constant at the room temperature of 300K. Determine the time required for the pressure in the tank to teach 300 kPa.
