Homework Help: Torque/power question

  1. Dec 12, 2004 #1
    Hey everyone, if I'm given the power of a motor (in kilowatts), and the torque of the motor, how would i go about calculating the speed of the drive shaft in RPM's? Thanks.

    First find w by doing P/T and then find n by doing 30w/pi.

    edit: P has to be in watts
