Answer:
Explanation:
A fluid, contained in a horizontal cylinder fitted with a frictionless leakproof piston, is continuously agitated by means of a stirrer passingthrough the cylinder cover. The cylinder diameter is 0.40 m. During thestirring process lasting 10 minutes, the piston slowly moves out adistance of 0.485 m against the atmosphere. The net work done by thefluid during the process is 2 kJ. The speed of the electric motor drivingthe stirrer is 840 rpm. Determine the torque in the shaft and the poweroutput of the motor.
