Consider a solar-pond power plant that operates on a simple ideal rankine cycle with refrigerant-134a as the working fluid. the refrigerant enters the turbine as a saturated vapor at 1.4 mpa and leaves at 0.65 mpa. the mass flow rate of the refrigerant is 3 kg/s. determine the thermal efficiency of the cycle. determine the power output of this plant.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Find the kinematic pressure of 160kpa. for air, r-287 j/ kg k. and hair al viscosity of air at a temperature of 50°c and an absolute (10 points) (b) find the dynamic viscosity of air at 110 °c. sutherland constant for air is 111k

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)
