Water with density 1000 kg/s enters a lawn sprinkler which is rotating at 500 RPM through its base at the steady rate of 1 L/s as shown. The exit area of each of the two nozzles is 30 mm^2 and the flow leaving each nozzle is in the tangential direction. The radius, r, from the axis of rotation to the centerline of each nozzle is 157 mm. The sprinkler tangential velocity in m/s is: Select one: a. 8.22 Nozzle exit area - 30 mm² Control volume b. 8220.52 c. 82.21 Flow out Flow out
