Determine the answer of the given question

Question- An Inland RBE 1803 Motor is directly coupled to a viscous mixer in which torque is proportional to speed and for which the torque is 300 oz-in when the mixer speed is 4000 rpm.

Part 1- At what torque, speed and mechanical power do the motor and mixer operate if the motor is made with the standard winding and the motor is powered at a constant 24 volts?

Part 2- At what torque, speed and mechanical power do the motor and mixer operate if the motor is made with the winding in 1) above and the motor is powered at a constant 19.05 volts?

Part 3- At what torque, speed and mechanical power do the motor and mixer operate if the motor is made with the standard winding and the motor is powered at a constant 19.05 volts?

I want experts help to find speed and mechanical power of motor.
