- Please AnswerSteam enters a nozzle at 400°C and 800 kPa with a velocity of 10 m/s and leaves at 375°C and 400 kPa while losing heat at a rate of 26.5 kW. For an inlet area of 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit. Use steam tables. The velocity of the steam at the nozzle exit is m/s. The volume flow rate of the steam at the nozzle exit is m3/s.arrow_forward2. A support hook was formed from a rectangular bar.

If the power generated by the turbine is 4.1 MW, determine the rate of heat loss from the steam. The enthalpies are h1 = 1448.6 Btu/lbm and h2 = 1130.7 Btu/lbm. The rate of heat loss from the steam is Btu/s.arrow_forward
