Analyze the boundary work done during the process having a rigid tank contains air at 500 kPa and 150°C. As a result of heat transfer to the surroundings, the temperature and pressure inside the tank drop to 65°C and 400 kPa, respectively.

Complete Question

Analyze the boundary work done during the process having a rigid tank contains air at 500 kPa and 150°C. As a result of heat transfer to the surroundings, the temperature and pressure inside the tank drop to 65°C and 400 kPa, respectively.

Determine the boundary work done during this process and heat Lose

a)  

b)  

Explanation:

From the question we are told that:

Pressure of air

Temperature of Air

Pressure drop

Temperature of drop

Generally the Constant Volume Process  is mathematically given by

Therefore

a)

Generally the equation for  boundary work w is mathematically given by

b)

Generally the equation for Heat Change is mathematically given by

Where

   C_v=Specific Heat capacity of Air
