The internal volume of the reducer is 0.2 3 and its mass is 25 . Evaluate the total force that must be provided by the surrounding pipes to support the reducer. The fluid is gasoline. Pro 4.87 A 30 reducing elbow is shown. The fluid is water. Evaluate the components of force that must be provided by the adjacent pipes to keep the elbow from moving. Pro 4.123 Water from a stationary nozzle impinges on a moving vane with turning angle = 120 . The vane moves away from the nozzle with constant speed, ? = 10 , and receives a jet that leaves the nozzle with speed ? = 30 . The nozzle has an exit area of 0.004 2 . Find the force that must be applied to maintain the vane speed constant....
