### Nozzle Design and P-v Diagram Analysis **Objective:** - Sketch and label the nozzle. - Sketch and label the process on a P-v (Pressure vs. Volume) diagram. - Include all numerical values relevant to the P-v diagram. **Problem Statement:** 7.15 The exit nozzle in a jet engine receives air at an entrance temperature and pressure of 1200 K and 150 kPa, respectively, with negligible kinetic energy. The air exits at a pressure of 80 kPa. The process is both reversible and adiabatic. Use a constant specific heat at a reference temperature of 300 K to find the exit velocity. **Diagram Explanation:** - **Nozzle Sketch:** The nozzle should be drawn to indicate the flow of air, labeling the inlet and exit points, showing the change in pressure from 150 kPa to 80 kPa. - **P-v Diagram:** The diagram should display the relationship between pressure (P) and volume (v) with clear notations: - Point 1: Initial state (1200 K, 150 kPa). - Point 2: Final state with exit pressure of 80 kPa. - The process will be depicted as a vertical line descending from the initial to the exit pressure, indicating a reversible adiabatic expansion. **Analysis:** - Assume constant specific heat at 300 K to determine the air's exit velocity using thermodynamic relations. - The temperature and pressure differences suggest significant kinetic energy conversion, ideal for calculating aerodynamic outputs for the jet engine.
