Elevated water tanks are used in a municipal water distribution system to provide adequate pressure. Compute the height (h) of the water tank above the ground sur­face to provide a static pressure of 410 kPa (60 psi). Compute the pressure in a build­ing that is 12 m (40 ft) above the ground surface. Typically, the pressure in a water dis­tribution system will range from 275 to 620 kPa (40-90 psi). Compute the range in h corresponding to this range in pressure. If the range in pressure is greater than this, multiple pressure zones may be required for the water distribution system.
