Water is pumped from a reservoir to another reservoir whose surface elevations are 1366 feet and 1657 feet, respectively. The connecting pipeline is 4 miles long and 10 inches in diameter. If the pressure during pumping is 65 psi at midlength of the pipe at elevation 1511.5 feet, what is the power? Assume the coefficient of friction is 0.02.
