### Required Information**NOTE:** This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Refrigerant-134a enters the condenser of a residential heat pump at 800 kPa and 50°C at a rate of 0.024 kg/s and leaves at 750 kPa subcooled by 3°C. The refrigerant enters the compressor at 200 kPa superheated by 4°C.(Take the required values from saturated refrigerant-134a tables.)#### Diagram ExplanationThe diagram illustrates the components of a heat pump system:1. **Compressor**: Increases the pressure of the refrigerant from 200 kPa to 800 kPa. Work input \( W_{\text{in}} \) is required for this process.2. **Condenser**: The refrigerant enters at 800 kPa and 50°C. The heat \( Q_H \) is rejected to the surroundings, and the refrigerant exits at 750 kPa.3. **Expansion Valve**: Lowers the pressure of the refrigerant to 200 kPa.4. **Evaporator**: Absorbs heat \( Q_L \) from the environment, completing the cycle.#### QuestionDetermine the Coefficient of Performance (COP) and the rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kPa.- The COP is [_____].- The rate of heat supplied to the heated room is [_____ kW].
