Points A and Bare separated by 3000 fi: of new 6 inch steel pipe. A discharge of 750 gpm of water at a temperature of 60°F flows from A to B. Point B is 60 ft in elevation above Point A. If the minimum pressure at B is 50 psi, what should be the pressure at A?
A garden hose of roughness 0.2 mm is used to irrigate a small farm, with water at 20°C. It is required to supply a flow rate of 20 /hr, to irrigate the farm in 6 hr. If the length and diameter of the hose are 50 m and 5 cm, respectively, determine the appropriate pressure that must be supplied at the inlet of the hose, to maintain the required flow rate.
