Steam enters a turbine operating at steady-state with a mass flow rate of 4600 kg/h. The turbine develops a power output of 1000 kW. At the inlet the pressure is 60 bars, the temperature is 400C and the velocity is 10 m/s. At the exit the pressure is 0.1 bar, the quality is 0.9 and the velocity is 50 m/s. Calculate the rate of heat transfer between the turbine and surroundings in kW.

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

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
