THERMODYNAMICS

PLEASE HELP WITH THESE TWO PROBLEMS I WILL UPVOTE THANK YOU

An insulated nozzle has saturated water vapor at 1000 kPa entering with a velocity of 50 m/s and at steady state. The pressure at the exit is 800 kPa with a quality of O.B. Determine the enthalpy at the outlet Multiple Choke 2390.5KO 23500 KG 25636N 25757 Air is contained in a piston cylinder device that is oriented vertically. The initial volume of the air is 1 m and the initial temperature is 27C Air is allowed to escape from the cylinder for a period of time unto the volume is 0.5 m. The piston has a mass that allows the pressure inside the tank to remain at 200 kPa. Heat transfer occur in such a way that the temperature remains constant Determine the total amount of heat transfer that occurs Multiple Choice O 3230 418 462
