Webwater flow over its surface. Pipe diameter affects the ratio of the cross sectional area to the wetted perimeter (R = A / P w). Surface roughness and irregularities affect the “friction” and turbulence of the flow, which is expressed as a Manning’s coefficient (n). The corrugation of metal culvert pipes is a major part of the coefficient. WebProper solder wetting will lead to well-made solder joints that can stand the test of time. You can often tell good solder wetting apart by its appearance — it will create a shiny, smooth-looking solder that has clearly reached maximum flow. Poor solder wetting, on the other hand, is often visible.
