Find mass flow rate volume flow rate at inlet average
Refrigerant R-134a enters a 1 cm constant diameter tube at 400 kPa and 30 degree C. The refrigerant leaves the tube at 100 kPa and 20 degree C with a velocity of 1 m/s. Calculate: mass flow rate volume flow rate at inlet average velocity at inlet.

Assuming no heat is lost to the surroundings and neglibible heat loss from the container. Determine the total change in entropy as a result of the mixing process.
Confirm that the pressure vessel will leak before burst when the surface length of the crack is smaller than this size by calculating the maximum size of the surface crack that can develop and still maintain the LBB criteria.
The system is then heated while the pressure is held constant until the volume doubles. Determine how much heat was added to the system.
