Thermodynamics Consultation Problems
A tank is connected to a pipe by a valve. The tank has a volume of 1m3, and it initially contains air at 150kPa and 27°C. The air in the pipe has a pressure of 750kPa and a temperature of 27°C. The tank is uninsulated. The valve is opened and lft open until the tank reaches pressure equilibrium with the air in the pipe and the air in the tank reaches 27°C.
Determine the mass of the air that has entered the tank and the heat transfer during the process, assuming that the air enters the tank with negligible velocity.
