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.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Agas is compressed from vi 0.3 m, p 1 bar to of v2 0.1 m3, p2--3 bar. pressure and volume are related linearly during the process. for the gas, find the work, in kj.
