Repeat Prob. 660 for a water flow rate of 50 L/s. Data from Problem 60. Water enters

Question:

Repeat Prob. 6–60 for a water flow rate of 50 L/s.

Data from Problem 60.

Water enters vertically and steadily at a rate of 35 L/s into the sprinkler shown in Fig. P6–60 with 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 any frictional effects, determine

The rotational speed of the sprinkler in rpm

The torque required to prevent the sprinkler from rotating.
