380-L tank contains steam, initially at 4008C, 3 bar. A
valve is opened, 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 the time, in s, at which 75% of the initial mass
remains in the tank; also determine the specific volume, in
m3
/kg, and pressure, in bar, in the tank at that time
