A tank of 0 1m3 volume is connected to a high-pressure air line; both line and tank are initially at a uniform temperature of 20 C.

The initial tank gage pressure is 100 kPa. The absolute line pressure is 2.0 MPa; the line is large enough so that its temperature and pressure may be assumed constant. The tank temperature is monitored by a fast-response thermocouple. At the instant after the valve is opened, the tank temperature rises at the rate of 0.05 C/s. Determine the instantaneous flow rate of air into the tank if heat transfer is neglected.
