relevant information is given in the figure below. The outlet area of each nozzle is facing the tangential direction, and the radius from the rotational axis to the midpoint of each nozzle is given as 200mm. If it is assumed that flow is frictionless, answer the following questions:: a.) Calculate the torque required to prevent rotation and this keeping the sprinkler stationary. b.) Calculate the torque required to prevent rotation, if the sprinkler head is moving at a speed of 500 rev. min1. c.) Calculate the speed of the sprinkler head if no torque is applied to prevent rotation
