Problem -1 A tank is initially empty. A liquid with p = 62.4 Ibm/ft is poured into the tank at a constant mass flow rate of mi = 7 lbm/s. The tank has cross-sectional area A = 0.2 fe, and the fluid in the tank has a %3D variable height H(t). There is a hole at the bottom of the tank. The fluid flows out of the tank at a rate proportional to the fluid height: rme = kH, where k= 1.4 lbm/ft/s. Find H(t). A sketch is given in Fig. P.1. Figure.P.1: Sketch of tank filling problem

Question B3 The engine of an aeroplane is equipped with an ideal convergent nozzle with an area ratio Ainlet 2.035 ( -A-2.035), as in Figure Q-B3. The aeroplane is flying at an altitude of 11 Aexit km where the atmospheric pressure and temperature are 0.23 bar and 216K respectively. You may assume the combustion gases entering the nozzle have the same property as air (i.e. y=1.40, R=287 J/kgK and Cp-1004.5J/kgK).
