Does friction in pipes cause heat and pressure drop?
Simple answer: Yes.
What is pressure drop?
Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream.This occurs when flow resistance resulting in frictional forces acts on the fluid while it is flowing through a tube. The major identifiers of the resistance include fluid viscosity and fluid velocity in the pipe. Pressure drop elevates the same way as shear forces inside the piping network. alliedallcityinc.com
