1. a) A barge is 10 m long, 5 m wide, 3.5 m deep, and weighs 1500 KN. How much of the barge will be below the water line? b) Determine the gage pressure in kPa at point, "a" shown in Figure 1.1, if liquid A has SG = 1.20 and liquid B has SG = 0.75. The liquid surrounding point "a" is water, and the tank on the left is open to the atmosphere. c) Liquid A 0.9 m -0.25 m Water 10.4 m -Liquid B 0.125 m Figure 1.1 a A 2 m wide wall as shown in Figure 1.2 below is fitted with a radial sluice gate at the base. Find the magnitude and direction of force on the gate. 2.5m 1m Fig. 1.2 1m
