PROBLEM: 1. A boiler feed pump delivers water at 100 °C which it draws from an open hotwell with a friction loss of 0.6 m in the intake pipe between it and and the hotwell. The barometer pressure is 73.6 cm Hg, and the value of the o, for the pump is 0.10. What must be the elevation of the water surface in the hotwell relative to that of the pump intake? The total pumping head is 73 m. 2. The diameter of the discharge pipe of a pump is 15 cm and that of the intake pipe is 20 cm. The pressure gage at the discharge reads 207 kPa, and the vacuum gage at the intake reads 25.4 cm. Hg. If Q = 85 ute of water and the Brake Power is 35.0, find the efficiency. The intake and liters sec discharge are of the same elevation.
