Hi.
I need some help in this question please [:(]
A gas flows into a rigid container initially evacuated . Assume that the inflow velocity is uniform at 2 m/s. The tube inlet diameter is 10 cm with the volume of the tank equal to 2000 litres. 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 perfect gas law P = ρRT, 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 300 K. Determine;
the rate of change of the gas density inside the tank, and the time required for the pressure in the tank to reach 300kPa
