[ /1] d) What volume in ml2H3OH in the solution. | (13) [1.5] e) If the solution is flowing through a pipeline at a rate of 250Lh. What is the molar flow rate of C2H3OH in g/s ? [ /3 ] Q4) A mercury manometer is connected at the base of a closed tank as shown in the figure below. The tank diameter is 1.4m and contains gasoline (SG 0.68) floating on water. a) Calculate the absolute air pressure above the gasoline. I /4.5] b) Calculate the gauge pressure at the base of the tank. [ 2.5] d) If gasoline is replaced with water with the same height (0.5m) and air pressure is the same. Do you expect the manometer differential reading to change? Explain your answer without calculation. [ /1.5]
