Question

The power of the airplane's piston engine is 185 hp, while the engine speed is 2500 r/min. (a) how much torque does the engine produce in that situation

Answer 1

The torque produced by the airplane's piston engine is approximately 68.386 N·m.

Step-by-step explanation:

To find the torque produced by the airplane's piston engine, we need to use the formula:

Torque = Power / Speed

Given that the power of the engine is 185 hp and the engine speed is 2500 r/min, we can convert the power into watts by multiplying it by 745.7 (1 hp = 745.7 watts). So, the power is 185 hp x 745.7 = 137771.5 watts.

Now, we can calculate the torque using the formula:

Torque = 137771.5 watts / (2500 revolutions per minute x 2π radians per revolution / 60 seconds per minute)

Simplifying this equation gives us:

Torque ≈ 68.386 N·m
