Water enters vertically and steadily at a rate of 35 L/s into the sprinkler shown in Figure Q.4. The sprinkler has unequal arms and unequal discharge areas. The smaller jet has a discharge area of 3 cm2 and a normal distance of 50 cm from the axis of rotation. The larger jet has a discharge area of 5 cm2 and a normal distance of 35 cm from the axis of rotation. Disregarding frictional effects, determine . (a) The shaft torque required to prevent the sprinkler from rotating. (b) The rotational speed of the sprinkler if the resisting torque is zero.
