3. Steam enters a diffuser operating at steady state with a pressure of 3 bar, a temperature of 200 °C, and a velocity of 100 m/s. Steam exits the diffuser as a saturated vapor, with a velocity of 10 m/s. Heat transfer occurs from the steam to its surroundings at a rate of 200 kJ/kg of steam flowing. Neglecting potential energy effects, determine the exit pressure, in bar. (Note: 1 kJ/kg-1000 m²/s²) (1) (2) Quick handwritten,no gpt.
