Solve both for my homework please Problem 7Steam enters an adiabatic diffuser at 200 kPa and 150°C with a velocity of 600 m/s. Determine the minimumvelocity that the steam can have at the outlet when the outlet pressure is 400 kPa.Problem 8A 0.6-ft³ well-insulated rigid can initially contains refrigerant-134a at 100 psia and 20°F. Now a crackdevelops in the can, and the refrigerant starts to leak out slowly. Assuming the refrigerant remaining in thecan has undergone a reversible, adiabatic process, determine the final mass in the can when the pressuredrops to 15 psia.

A 1.5-ft³rigid tank contains saturated refrigerant-134 at 170 psia. Initially, 20 percent of the volume is occupied by liquid and the rest by vapor. A valve at the top of the tank is now opened, and vapor is allowed to escape slowly from the tank. Heat is transferred to the refrigerant such that the pressure inside the tank remains constant. The valve is closed when the last drop of liquid in the tank is vaporized. Determine the total heat transfer for this process. R-134a, Sat. mixture P = 170 psia V = 1.5 ft³
