Question

If a shaft turns at 150 rpm under a torque of 1500 Nm, then power transmitted is

• A. 15π kW
• B. 10π kM
• C. 7.5π kM
• D. 5π kM

Answer 1

Answer:

C. 7.5π kM

Given: Speed, N = 150 rpm, Torque, T = 1500Nm .. $Power =$ $\frac{2\pi NT}{60}$=$\frac {2\times π\times 150\times1500}{60} = 7.5π kW$
