Question

If an engine at sea level produces 100 horsepower, how many horsepower would it develop at 6,000 feet of altitude?

Answer 1

Answer:

Power develop at 6000 ft = 100 - 18 = 82 hp

Given:

Power produced by the engine at sea level = 100 hp

Explanation:

For each 1000 ft rise above the sea level, the power loss of the engine is about 3%

Therefore,

1000 ft - 3% loss

6000 ft - $3\times 6 = 18 %$

At 6000 ft, the power loss is 18% or 18 hp

Now,

Power develop at 6000 ft = Power at sea level - Power loss at 6000 ft

Power develop at 6000 ft = 100 - 18 = 82 hp
