1. A fuel pump is delivering 10 gallons per minute of oil with a specific gravity
of 0.83. the total head is 9.15m. Find how much energy/power does the
pump consumes in kJ per hour.
2. A pump driven by an electrical motor moves 25 gallons per minute of water
from a reservoir A to B, lifting the water to a head of 245 ft. The efficiency
of the pump is 65%. Neglecting velocity head, friction head and minor
losses; What power input in horse power is required?
