Question

11-Water enters vertically and steadily at a rate of 20L/s into the sprinkler with unequal arms and unequal discharge areas. The smaller jet has a discharge area of 2 cm2and a normal distance of 45 cm from the axis of rotation. The larger jet has a discharge area of 5 cm2and a normal distance of 25 cm from the axis of rotation. Disregarding any frictional effects, determine (a) the rotational speed of the sprinkler in rpm and (b) the torque required to prevent the sprinkler from rotating.

Answer 1

a. Speed =20m/s

Torque =631 rpm
