P2.11 In Fig. P2.11, pressure gage A reads 1.5kPa (gage). The fluids are at 20°C. Determine
the elevations z, in meters, of the liquid levels in the open piezometer tubes B and C.
P2.31 In Fig. P2.31 all fluids are at 20°C. Determine the pressure difference (Pa) between
points A and B.
P2.46 In Fig. P2.46 both ends of the manometer are open to the atmosphere. Estimate the
specific gravity of fluid X.
P2.68 Isosceles triangle gate AB in Fig. P2.68 is hinged at A and weighs 1500 N. What
horizontal force P is required at point B for equilibrium?
P2.73 Gate AB is 5 ft wide into the paper and opens to let fresh water out when the ocean
tide is dropping. The hinge at A is 2 ft above the freshwater level. At what ocean level h will
the gate first open? Neglect the gate weight.
