QUESTION 2 (25 MARKS) 65 kPa 75 cm Oil 50-0.72 Air Water 30 m Water Mercury SG 13.6 Figure Q2(a) a. The gage pressure of the air inside the tank shown in Figure Q2(a) is measured to be 65 kPa. Determine the differential heighth of the mercury column (CO2:PO2 - 5 Marks) wall water gate B i. Figure Q2(b) b. The water gate AB in Figure 2(b) is a quarter circle with radius r= 5m and 2m wide. The distance of the gate from the water surface is given by h. The gate is hinged at point B. Find the force FR and its line of action, just sufficient to keep the gate from opening, given h = 2m (CO2:P02 - 12 Marks) If a similar water gate with the same dimensions as above, is being designed for a new reservoir, but to hold more volume of water (h = 5m), calculate Fr just sufficient to keep the gate from opening. Comment on the difference from b) above. (CO3:PO2-8 Marks)
