Air is stored in a large chamber at 450K and 150kPa. The gas is discharged into a room during a converging nozzle with an exit area of 30 cm2. The ambient room pressure is 100 kPa and the flow through the nozzle is isentropic.
1. What is the mass flow rate of the air?
2. If the room pressure can be lowered, what is the maximum possible mass flow rate for the air?
