In an ideal rankine cycle steam enters the turbine at 8 mpa and 540c the condenser pressure is 15kpa. the net power produced by cycle is 150mw. determine (a) the heat transfer to the water in the steam generator, (b) the heat transfer to the produced by the cycle is 120 cooling water in the condenser, (c) the cycle thermal efficiency, (d) the mass flow rate of coolin condenser at 20°c and leaves at 35 c

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
