# Rankine Cycle Power Plant Schematic and Data## Schematic Diagram ExplanationThe diagram illustrates a basic Rankine Cycle power plant, which consists of the following key components:1. **Pump (1):** Increases the pressure of the fluid, typically water.2. **Economizer (2):** Preheats the fluid before it enters the steam generator.3. **Steam Generator (3):** Heats the fluid, converting water into steam.4. **Turbine (5):** Expands the steam to produce work.5. **Condenser (6):** Cools the steam back into water using cooling water.6. **Cycle Outlet and Pump Inlet (7):** Feeds condensed water back to the pump to repeat the cycle.Arrows indicate the flow of the working fluid through the plant.## Operational DataThe power plant is reported to be operating at the following peak load conditions:- **Power to pump:** 300 kW- **Rate of steam flow:** 25 kg/s- **Cooling water temperature at condenser inlet:** 13 °C- **Cooling water temperature at condenser outlet:** 34 °C## Measurement DataMeasurements taken at various points in the power plant are summarized below:| Data Point | Pressure (kPa) | Temp.

Example -5.2- It is required to pump cooling water from storage pond to a condenser in a process plant situated 10 m above the level of the pond. 200 m of 74.2 mm i.d. pipe is available and the pump has the characteristics given below. The head loss in the condenser is equivalent to 16 velocity heads based on the flow in the 74.2 mm pipe.
