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-direction with speed V v which is less than V j . Find the force necessary to keep the vane moving at a constant velocity, that is, to prevent it from accelerating. 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 ft 2 . The density of air entering is 1.236 kg / m 3 .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
