the pressure necessary to extend the fracture once initiated. The fracture extension pressure may rise slightly with increasing fracture length and/or height because of friction pressure drop down the length of the fracture. Fracture roughness, fracture w
a dimensionless value expressing the roughness of the pipe.
the interior surface metal roughness of a pipe. Rough pipes have higher friction.
roughness of a hole.
n: roughness or irregularity of a solid surface.
a measurement of roughness of the surface of a passage.
a consideration in fluid friction calculations. A pipe with a polished surface may have 1/10th the friction and flow 10 to 25% more fluid at the same pressure drop (depending on pipe diameter),than a pipe with a corroded or heavily fouled surface.
