A certain Geothermal Power Plant shows that 1,700,000 kg/hr of pressurized ground water is available at 17.5MPa and 330°C. The water will be throttled to a pressure of 1.7MPa to produce wet steam and this mixture will be passed through a water separator to remove the water droplets so that saturated steam at 1.7MPa is available at the entrance of the Turbine.

Thermodynamics Question: Refrigerant – 134a is to be cooled by water in a condenser. The refrigerant enters the insulated condenser with a mass flow rate of 6 kg/min at 1 MPa, 70 oC and leaves at 35 oC. The cooling water (compressed liquid) enters at 300 kPa and 15 oC and leaves at 25 oC. Neglecting any pressure drops, kinetic and potential energy changes in the pipes, determine (a) the mass flow rate of the cooling water required and (b) the heat transfer rate from the refrigerant to water.
Steam at 6000 kPa and 500°C enters a steady-flow turbine. The steam expands in the turbine while doing work until the pressure is 1000 kPa. When the pressure is 1000 kPa, 10 percent of the steam is removed from the turbine for other uses. The remaining 90 percent of the steam continues to expand through the turbine while doing work and leaves the turbine at 10 kPa. The entire expansion process by the steam through the turbine is reversible and adiabatic. Sketch the process on a T-s diagram with respect to the saturation lines. Be sure to label the data states and the lines of constant pressure?

Steam is to be condensed in the condenser of a steam power plant at a temperature of 60°C with cooling water from a nearby lake, which enters the tubes of the condenser at 18°C at a rate of 75 kg/s and leaves at 27°C. Assuming the condenser to be perfectly insulated, determine the rate of entropy generation in the condenser.
Consider an isentropic steam turbine shown in Figure 2. Steam at 6 MPa and 400℃ is supplied to the throttle inlet, and the turbine exhaust pressure is set at 70 kPa. Analyse this isentropic steam turbine and answer the following questions. (a) How much work is being produced by the isentropic steam turbine in Figure 2, in kJ/kg? (b) Consider the case where the throttle valve is closed to a point where the inlet pressure is halved. Compare the work produced under this condition with the work produced in (a). (c) Now let us remove the throttle valve, and, instead of steam, let air expand in the turbine from an inlet state of 2200 kPa and 300℃ to an outlet pressure of 200 kPa. If the turbine is now an adiabatic turbine of 90% isentropic efficiency, how much work is being produced by the turbine in contrast to the previous one in (b)? (d) How much entropy is generated by this new setup in (c)?
