Question

an airplane engine develops total thrust of 10000N when it is flying at 250m/s. Calculate the power developed by the engine in horse power.

Answer 1

The power developed by the airplane engine flying at 250 m/s with a thrust of 10,000 N is approximately 2,500,000 W or 3352.8 hp.

Step-by-step explanation:

To calculate the power developed by the airplane engine in horsepower, we use the formula for power when force and velocity are known:

Power (P) = Force (F) × Velocity (v)

Where the thrust (force) is 10,000 N and the velocity of the airplane is 250 m/s. Inserting these values gives us:

P = 10,000 N × 250 m/s = 2,500,000 W (watts)

To convert this power into horsepower (hp), we use the fact that 1 horsepower is equivalent to 746 watts.

Power in horsepower = Power in watts / 746

Power in horsepower = 2,500,000 W / 746 ≈ 3352.8 hp
