A 4 m diameter sphere is embedded in insulation. The sphere contains a liquid-ice mixture maintained at 0 deg C. The ambient temperature surrounding the insulation is 25 deg C.
Steam expands isentropic ally through a turbine from 6MPa and 600C to 9.593 kPa. Write mass, energy, and entropy balances for this process. Calculate the power output if the mass flow is 2 kg/s.
Saturated liquid water at 25°C is pumped to a pressure of 5MPa in an isothermal process. The specific work required by the pump to pressurize the water to 5MPa can be found as the change in enthalpy of the water from the inlet pressure to the outlet ..
