Unlike other calculators, you are NOT confined to inputting diameter in inches, velocity in miles per hour, etc. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the K-value method, also known as the Resistance Coefficient, Velocity Head, Excess Head or Crane method. Gradient = 0. Or in a long pipe connecting two reservoirs, the difference in elevation between the reservoirs gives pressure to the pipe that is used up evenly foot by foot to push the water against roughness friction in the pipe.
