Areheat rankine cycle operates a boiler at 7 mpa with a super-heater outlet temperature of 500°c, 100% hp turbine outlet steam quality, re-heater outlet temperature of 400 °c, and lp turbine outlet (condenser inlet) steam quality of 100%. assuming isentropic pump and turbine, the thermal efficiency of this cycle would be %.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
