**Pipe Flow Calculating Head Loss Example - YouTube**

Example calculation Calculate the pipe friction loss of a 2 1/12” schedule 40 (2.469” internal pipe diameter) new steel pipe with a flow rate of 149 gpm for water at 60F and a pipe length of 50 feet.... Summary. Fittings such as elbows, tees and valves represent a significant component of the pressure loss in most pipe systems. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method.

Pipe friction head loss + (HFP1-2 Fittings friction head loss + (HFF1-2 Equipment friction head loss + (HEQ1-2 Check valve head loss + (HCHECK Total static head + z2 – z1 Velocity head difference + v22/2g – v12/2g Tank pressure head difference + H1 – H2 Total head (ft fluid) = (HP Table 5. Summary of the calculation results of the total head.... In Chezy’s formula, friction loss is calculated by using a coefficient reflecting the roughness of the pipe, the internal hydraulic radius of the pipe and the hydraulic slope, which is the friction loss per unit length of pipe.

- Example 1 The accepted transition Reynolds number for flow in a circular pipe is Re 2,300dc, ρUd μ Dimensional analysis shows that the head loss can be represented by 2 2 m f LU hf dg = (9) The parameter f is called the Darcy friction factor. The friction factor or coefficient of resistance is a non-dimensional measure of the resistance offered by the wall to flow through the pipe
