### 10D. Pipe Friction Pressure loss Using Equation 10.23 or 10.24 Back to Main

This page is used to determine friction pressure loss. A direct solution for friction pressure loss is possible by algebraic manipulation of the basic equations.

Small Pipe, (Equation 10.23)

Large Pipe, (Equation 10.24)

# Where: d = diameter

q = volumetric flow rate

r = density

m = viscosity

L = length of line

= mass/force conversion constant

= Frictional pressure drop

The units are defined as those listed on page 321. To carry out the Pipe Friction Pressure Loss calculation the Liquid viscosity, Liquid density, Pipe length, Inside diameter, and Flow rate the fluid must be entered into their entry space. To do so use the mouse to click the curser in their entry space and input the data. Once this has been done, select Run to execute the solution.
