Steam at a pressure of 14.7psia and a temperature of 320deg F enters a diffuser inlet at a velocity of 500ft/s. The steam decelerates in the diffuser to a velocity of 100ft/s. The steam leaves the diffuser as saturated vapor at 240 deg F. The area of the diffuser outlet is 120 square inches.

What is the mass flow rate of steam through the diffuser, lbm/s?

What is the heat transfer from the sides of the diffuser for these conditions? btu/s

What is the inlet area of the diffuser, square feet?

R-134a leaves a refrigeration device’s condenser as a saturated liquid at 35 deg C and enters a throttling device where the pressure drops to 0.31 MPa. What is the enthalpy entering and leaving the throttling device?

Steam at a temperature of 400 deg F and a pressure of 100psia enters a steam turbine with a flow rate of 10 lbm/s. The steam leaves the turbine at a pressure of 0.95 psia and a temperature of 100 deg F. What is the theoretical power output of the turbine btu/h and kW Assume no heat losses from the walls of the turbine. Also assume no ke or pe changes.
