(a) A Steam power plant operates on a simple ideal Rankine eycle (Figure 2). Determine the thermal efficiency of this cycle when it is operated so that the liquid enters the pump as a saturated liquid. Boiker P- 6000 Pa O Te 0 C Pump Turbine P-50 kPa Condenser undund Figure 2

1. Consider the following schematic of a power plant (operating in what is called a 'Rankine Cycle') Turbine Steam generator Condenser Coling water Economiaer The power plant control room reports that the plant is operating continuously at the following peak load conditions: a. Power to pump = 300KW b. Rate of steam flow = 25 kg/s c. Cooling water temperature at condenser inlet = 13 C d. Cooling water temperature at condenser outlet = 34 C Additionally, the following measurements were made at various points in the piping connecting the power plant components Data Pressure Temp. Quality enthalpy Specific Velocity (kJ/kg) point (kPa) volume (m/s) (m3/kg) (C) (x) 1 6200 2 6100 43 5900 177 ---- 4. 5700 493 ----- 5 5500 482 ----- 6 103 0.94 183 7 96 43 -----

Plz help me determine the rankine cycle Or can someone do the rankine cycle on this and how this works

Cold storage uses R134a, the evaporator temperature is -7C and the condenser temperature is 32C. The cooling load is 5.3103 kJ/min. The cycle is ideal. Determine: 1. Mass flowrate of the refrigerant. 2. Coefficient of Performance (COP). - If the water condenser is used that enter at 24C and exit at 30C. determine the water flowrate.
