Steam enters a turbine steadily at 7 mpa and 600°c with a velocity of 60 m/s and leaves at 25 kpa with a quality of 95 percent. a heat loss of 21 kj/kg occurs during the process. the inlet area of the turbine is 150 cm2, and the exit area is 1400 cm2. the specific volumes and enthalpies are v1 = 0.05567 m3/kg, h1 = 3650.6 kj/kg, v2 = 5.8933 m3/kg, and h2 = 2500.2 kj/kg. determine

(a) flowrate of the steam,

(b) exit velocity, and

(c) the power output.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
