Asteam turbine operating with a steady mass flow rate of 3.00 kg/s produces power output of 3.0 mw the inlet conditions are p1 = 60 bar and ti = 600°c, and outlet conditions are p2 0.20 bar and x2 0.97. the heat transfer from the turbine occurs at a boundary temperature tb = 350 k. neglect kinetic and potential energy changes. assume that the given pressures are absolute
(a) on a t-s diagram, indicate the process including lines of constant pressure.
(b) determine the rate of heat transfer to the surroundings, in kw. (c) determine the entropy generation rate, in kw/k

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)
