A380-l tank contains steam, initially at 500oc, 3 bar. a valve is opened for 10 seconds and steam flows out of the tank at a constant mass flow rate of 0.005 kg/s. during steam removal, a heater maintains the temperature within the tank constant. determine final mass remaining in the tank, in kg, and the final pressure in the tank, in bar.
