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 -
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
