Determine the size of the gravity main to convey water from source to the treatment facility. Assume that water is provided at a rate of 150 L day-1 per person (total flow rate: 0.434 m3 s-1) through a cast iron pipe. Compute the minimal diameter of the pipe if all the flow for a day is pumped to the facility within 12 hours (i.e., actual flow rate: 0.864 m3 s-1). Note: consider the kinematic viscosity of water to be 10-6 m2 s-1.16.

A hilltop subdivision takes water from a river 500 ft below it during the night through a pump storage facility. When morning comes, water will be returned to the river with the use of turbines. Entrance and exit pipes both measure 30-in in diameter and both are 2500 ft long and the flow rate is 20,000 gpm. What should be the pumping power required in horsepower if friction loss amounts to 15 ft of water? Assume that the pump is 100% efficient.
