Question 17
XE-ENAT2 marksNeeds review
Air at a pressure of 1 MPa and 300 K is flowing in a pipe. An insulated evacuated rigid tank is connected to this pipe through an insulated valve. The volume of the tank is 1 m³. The valve is opened and the tank is filled with air until the pressure in the tank is 1 MPa. Subsequently, the valve is closed. Consider air to be an ideal gas and neglect bulk kinetic and potential energy. The final temperature of air in the tank is __________ K (1 decimal place).
Specific heat capacity of air at constant pressure
kJ/(kgK) and characteristic gas constant for air = 0.287 kJ/(kgK)Log in to check the answer
