A fluid is pumped at the rate of 10 lb/sec to a height of 55 ft. The horse power required is _____________ hp?
Correct answer: A. 1
- A. 1
- B. 10/55
- C. 5.5
- D. 1/55
Explanation
The hydraulic power is weight flow rate multiplied by head: 10 lb/s × 55 ft = 550 ft·lb/s. Since 1 horsepower equals approximately 550 ft·lb/s, the required power is 1 hp.
