Air at a temperature of 40°C flows into the nozzle at 6 m/s and then exits to the atmosphere at B, where the temperature is 0°C. Determine the pressure at A.

Water flows through the transition at 0.3 m³/s, which causes the water to rise within the piezometer at A to a height of h_A
= 350 mm. Determine the height h_B.
