find the pressure head at m in feet of fluid A when fluid A is seawater (sp.gr. 1.03), fluid B is bromoform (sp.gr. 2.87) 2. Manometers are attached to a closed tank containing oil (0.85), water, molasses (1.5) and air (4 kPa). Compute the pressure head of oil at tube E. Also find x. 3. In figure 3, compute the pressure difference between A and B of the venturi meter shown. 4. A cylindrical reservoir 6 m in diameter and 10 m high, contains 5 m of oil (S = 0.82), 2.5 m of water and 1.5 m of mercury (S = 13.6). Compute the total normal pressure on the interior sides and at the bottom of the reservoir. Fluid A m fig.
