air supply line air { V= 0.75 m3 oshg A 0.75 ms rigid tank initially contains of air at 295 K (State 1). The tank is connected to a supply line through a valve: the air in the supply line is at 700 kPa and 300 K. The valve is opened, and air is allowed to enter the tank until the mass of air in the tank reaches (State 2). A thermometer placed in the tank indicates that the air temperature in State 2 is 325 K. 2.5kg Determine the heat transferred to the tank during the process in (kJ). Give your answer in kJ to 3 significant figures. Data: Cp = 1,005 kJ/(kg K), CV = 0.718 kJ/(kg K), R = 0.2870 kJ/(kg)
