20. A fluid contained in a horizontal cylinder fitted with a frictionless leak-proof piston is continuously agitated by a stirrer passing through the cylinder cover. During stirring operation for 10 minutesthe piston slowly moves outwards through 20 cm distance against a pressure of 1 bar. The stirreturns 600 revolutions and the net work done on the fluid during the process is estimated to be2kJ. If the cylinder diameter is 40 cm, estimate the torque in the driving shaft and the shaftoutput of the motor.(Ans. 0.1197 Nm, 0.00752 kW) |
