Name:________________________ ME 332, Spring 2009 Exam 2 Problem 1 (50 points): The nozzle assembly on a fire-fighting boat is fixed to the boat deck by several heavy bolts. The nozzle is directed at an angle of 35 degrees to the horizontal and has an outlet diameter of in. 3 = d Water flows into the assembly from below the deck through an opening with diameter in. 10 = D , gage pressure 50 psi and flow-rate min. gal 750 = Q . The volume of the flow passages within the nozzle assembly is 3 in. 1500 = 2200 N , and the weight of the assembly itself is lb 175 = N W . Assume that the flow is steady, with uniform profiles at the inlet and the outlet. i) Draw the control volume that you will use for a mass and momentum analysis of this flow. The net horizontal and vertical anchoring forces required from the bolts should appear as reaction forces on the control surface. Draw vectors for these and any other surface and body forces that should be considered. Label the inlet and outlet surfaces as
