A 1-m3 rigid tank initially contains air at 150 KPa, 300 K. The tank is connected through a valve to a supply line at 300 KPa, 380 K. When the final pressure in the tank reaches 300 KPa the valve is closed. Due to heat transfer from the tank, the final tank temperature is measured at 320 K. Calculate: a) The mass of the air that has entered the tank, and b) The heat transfer from the tank. (Use Table for air enthalpy and internal energy property values)
