1.-The three vessels (1, 2 and 3) shown below have different S.G..: S.G.1 = 1.02, S.G.2= 1.39, S.G3 = 1.6. Give the value of the hydrostatic pressure at point A located at 30 cm depth in vessel 1, at point B located at 5 cm depth in vessel 2, and at 15 cm depth in vessel 3 in (a) psi , (b) in mm H2O, and (c) the absolute pressure (mm Hg) in all 3 vessels at points A, B, and C if the atmospheric pressure is 790 mm Hg on that day.

2.- A conical container of height h (25 cm) and radius R (15 cm) is filled with water (S.G. = 1). Which will be greater, (a) the weight (W) of the water contained in the container or (b) the hydrostatic force exerted by the water at the base of the container? Give the result in dynes/cm? (c) If there is a difference between answers a and b, argue why this is so.
