Problem 4.159 [Difficulty: 4] CS moving at speed U c d D = 75 mm M = 35 kg Given: Water jet striking disk Find: Plot mass versus flow rate to find flow rate for a steady height of 3 m Solution: Basic equations: Bernoulli; Momentum flux in z direction (treated as upwards) p ρ V 2 2 + gz + constant = Assumptions: 1) Steady flow 2) Incompressible flow 3) Atmospheric pressure in jet 4) Uniform flow (All in jet) The Bernoulli equation becomes V 0 2 2 g0 + V 1 2 2 gh + = V 1 V 0 2 2g h = The momentum equation becomes M g w 1 ρ V 1 A 1 () w 2 ρ V 2 A 2 + = V 1 ρ V 1 A 1
