The closed tank of fig. p.2.34 is filled with water and is 5 ft long. the pressure gage on the tank reads 7 psi. determine: (a) the height, h, in the open water column, (b) the gage pressure acting on the bottom tank surface ab, and (c) the absolute pressure of the air in the top of the tank if the local atmospheric pressure is 14.7 ps

like poles repel so keep pushing north to north and repels funny to see this
