Water at 60°F is to flow by gravity between two points, 2 mi apart, at the rate of 13 500 gal/min. The upper end is 130 ft higher than the lower end. What size concrete pipe is required? Assume that the pressure at both ends of the pipe is negligible.

Water at 38°C flows from A to B through 244 m of average 300-mm-I.D. cast iron pipe (e = 0.00061 m).Point B is 9.1 m above A, and the pressure at B must be maintained at 138 kPa. If 0.222 m3/s is to flowthrough the pipe, what must be the pressure at A? Ans. 314 kPa (show the complete solution with diagram) [Note: Indicate the formula used in determining the friction factor. (Colebrook Equation, Haaland Equation, andor Swamee Jain Equation). If not given, Use properties of fluid based ontemperature available ontheinternet.E.g. (density, viscosity). Apply roughness of pipe values from https://www.pipeflow.com/pipe-pressure-drop-calculations/pipe-roughness]

Water flows from a pressurized tank (at 150 kPa gauge) to an open tank 15m above. What is the pressure head developed by the flow?
