Unformatted text preview: Prof. Daniel J. Bodony AE311 , Fall 2011 HW #2 Due 5 pm Friday, September 16, in the AE311 dropbox Problem 1 Consider the steady flow of a water jet impinging on a stationary vane as shown below. Determine the force required to hold the vane in place. Assume the jet follows the surface of the vane in a smooth manner and has the same shape and area at the exit so that the pressure in the fluid is the same as the ambient pressure. Problem 2 Consider the same vane as in Problem 2 now in uniform motion along the x—direcrion with speed Vv which is less than V}. Find the force necessary to keep the vane moving at a constant velocity, that is, to prevent it from accelerating. L-— ‘- #3 —|\- Control surface Fluid velocities are t F: moving at velocity V” F relative to vane v Problem 3 A jet engine is being tested statically on a test stand. The inlet velocity is 152.4 m/s and the exhaust gases leave at a velocity of 1066.8 m/s. The air at the inlet and the exhaust gases at the exit are at atmospheric pressure. The fuel—to-air ratio is 1/50 and the inlet and exhaust areas are both 2 ftz. The density of air entering is 1.236 kg/m3. Determine the force required to hold the jet'engine stationary.
