Acarnot heat engine receives heat from a reservoir at 900°c at a rate of 800 kj/min and rejects the waste heat to the ambient air at 27°c. the entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5°c and transfers it to the same ambient air at 27°c. determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air.

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)
