b) A cylindrical tank contains water at a height of 55 mm as shown in Figure 1. Inside is a smaller pen cylindrical tank containing cleaning fluid at height, h. If P3 is 13.40 kPa gage and Pc is 13.42 kPa gage, calculate gage pressure Pa and height, h of cleaning fluid. Given specific gravity of cleaning fluid is 0.8. Assume that the cleaning fluid is prevented from moving to the top of the tank. [6 marks] Air Water 55 mm h Kerosene P3 Pc Figure 1: Cylindrical tank
