Unformatted text preview: Prof. Daniel J. Bodony AE311, Fall 2011 HW #5 Due 5 pm Friday, October 14, in the AE311 dropbox Problem 1 A nozzle for a spray system is designed to produce a flat radial sheet of water. The sheet leaves the nozzle at velocity U 2 = 15 m / s, covers 180 ◦ of arc, and has thickness t = 2 . 5 mm. The nozzle discharge radius is R = 75 mm. The water supply pipe is 25 mm in diameter and the inlet pressure is p 1 = 200 kPa. Assume the inlet velocity is uniform over the cross-section of the pipe. Assume the water leaves the nozzle with a uniform velocity, and empties into a room at standard atmospheric pressure at sea level. Evaluate the axial force exerted by the spray nozzle on the coupling. Water Problem 2 Given the velocity potential φ = x 2 − y 2 , find the velocity field u = ( u , v ), and the stream function ψ . Plot the streamlines, ψ = constant, as solid lines. On the same graph, plot the equipotential lines, φ = constant, as dashed lines. Is there a stagnation point in the flow?lines....
