Question 1 (15 marks) It is known that the temperature of the earth's atmosphere drops about 10C for every 1km above the earth. If the temperature of the air on the ground is 12C and the pressure is 760 mmHg. At what height above the earth is the pressure 300mmHg ? Assume the air behaves as an ideal gas. Use the following Hydrostatic equilibrium equation: dp+gdz=0 Remember: a+bx1dx=b1ln(a+bx) Question 2 (25 marks) Crude Oil as atmospheric conditions is pumped from tank 1 to tank 2 at a flow rate of 85 m3/hr. The depth of the liquid above the draw-off connection in tank 1 is 5m. The line from the draw-off is 50m in length and is a 76.2mm schedule 80 commercial steel pipe. The oil discharges into the atmosphere below the draw-off connection of the tank. Calculate the height of tank 2 below the draw off connection of tank 1 (indicated as m in Figure 1 -include all the fittings in your calculations). Additionally Figure 2, Table 13 are given below for your use. Figure 1: Depiction of Question 1 problem Additional Information - SG of crude oil is 0.93 - Viscosity of crude oil is 4CP(1CP=0.001 Pas) - The valves are % open
