Textbook Answer: About 10 m/s.

**EP 6.4** **Given:** Air flows into the gas heater at a steady rate, such that at point A its absolute pressure is 203 kPa, its temperature is 20°C, and its velocity is 15 m/s. When it exits at point B, it has an absolute pressure of 150 kPa and a temperature of 75°C. **Diagram Explanation:** The diagram shows a rectangular gas heater with an air inlet at point A and an outlet at point B. At point A, there is an arrow pointing into the heater labeled with a velocity of 15 m/s and a temperature of 20°C. The diameter of the inlet is 100 mm. Inside the heater, coils are depicted, representing the heating element. At point B, the air exits with a diameter of 150 mm, and the outlet velocity is denoted as \( V_B \). **Find:** Determine the velocity of the air at point B (\( V_B \)).
