Boiler Heat Input An ideal reheat Rankine cycle is characterized by a steam generator pressure of 9MPa, superheat temperature of both the reheated steam and inlet turbine steam of 560 oC, reheat pressure of 1000 kPa, and a condenser pressure of 10 kPa. Determine the total heat input to the system in the boiler. qin = 4040 kJ/kg

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)
