Unformatted text preview: gage pressure is 96 kPa. The water discharges to atmospheric pressure. Assume properties are uniform over the inlet and outlet areas: A 1 = 2500 mm 2 , A 2 = 550 mm 2 , and V 1 = 4 m/s. Find the horizontal component of force required to hold the elbow in place 4. A rocket sled accelerates from rest on a level track with negligible air and rolling resistances. The initial mass of the sled is M o = 500 kg. The rocket initially contains 150 kg of fuel. The rocket motor burns fuel at constant rate m = 15 kg/s. Exhaust gases leave the rocket nozzle uniformly and axially at V e = 2500 m/s relative to the nozzle, and the pressure is atmospheric. Find the maximum speed reached by the rocket sled. Calculate the maximum acceleration of the sled during the run....
