Use PIPE-FLO® to calculate the head loss and pressure drop in a length of pipe that includes a filter. The pipe is a horizontal 6-in Schedule 40 pipe. The total length of pipe is 45 ft and the manufacturer of the filter specifies that it has a K-factor value of 0.82. Water at 60°F flows through the system at 9 ft/s. The pressure in the tank is 75 psig.
