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
2. A large sheet of glass 2” thick is initially at 300oF throughout. It is plunged into a stream of running water having a temperature of 60oF. How long will it take to cool the glass to an average temperature of 100oF. For glass k = 0.40BTU/ft-hroF, ρ = 155 lb/ft3 and Cp = 0.20 BTU/lboF.
Figure shows a heat exchanger designed to cool 5250 kg/h of an ethyl alcohol solution (Cp = 3810 J/kg. °C) from 66 °C to 39 °C.Water (Cp = 4200 J/kg. °C) at 10 °C is pumped at 4750 kg/h to cool the solution. The tube side fluid flows in a circular pipe with an outside diameter of 25 mm. The overall heat transfer coefficient is (6.84x10^2) W/(m².°C). Find the tube length 'L' for one pass of a two-pass parallel flow double-pipe heat exchanger as shown in Figure. Answer should be in m with three significant figures.
