1.A gate having a cross section shown ( no diagram ) closes an opening 5 ft wide and 4 ft high in a water reservoir. its center of gravity is one foot to the left of AC and 2 ft above BC. Determine horizontal reaction developed on the gate at C.
2.A liquid has the peculiar property that its mass density increases linearly with depth according to the expression p = p_water (1+0.01d) where d is the depth below the liquid surface in meters. At a depth of 10 m, what is the gage pressure?
