1.

to maintain a rotation at a uniform angular speed of 200m/s, an engine needs to transmit a torque of 180 N.m, what is the power of the engine required?

Answer»

Angular speed of the rotor, ω = 200 rad/sTorque required, τ = 180 NmThe power of the rotor (P) is related to torque and angular speed by the relation:P= τω= 180 × 200 = 36 × 103= 36 kWHence, the power required by the engine is 36 kW.
