A horizontal pipe, 12 inches in diameter and 2500 ft in length, carries a discharge of 0.25 ft3 /s for a thermal power plant from a reservoir, as shown in Figure P5.26. Calculate the pressure in the pipe at a distance of 1000 ft from the reservoir. The head loss in the pipe is given as

where L is the length of the pipe from the reservoir, d is the diameter of the pipe, V is the mean water velocity in the pipe, and g is the acceleration of gravity.
