1. Moody Friction Factor Calculator By Robert Porter Justin Alder Justin Alder

2. Introduction Easily calculate the moody friction factor Easily calculate the moody friction factor Used in correlation with the thermo properties calculator (designed by Used in correlation with the thermo properties calculator (designed by Jon Isaacson). (an approximation of the implicit Colebrook–White equation) Swamee–Jain equation (an approximation of the implicit Colebrook–White equation) (Swamee, P.K.; Jain, A.K. (1976). "Explicit equations for pipe-flow problems". Journal of the Hydraulics Division (ASCE) 102 (5): 657–664)

3. The Works Use the density and dynamic viscosity at the given temperature of the desired fluid Use the Jon Isaacson TP calculator to get the density and dynamic viscosity at the given temperature of the desired fluid Input: Input: density, dynamic viscosity, diameter, pipe type, mean velocity/mass flow rate/volumetric flow rate density, dynamic viscosity, diameter, pipe type, mean velocity/mass flow rate/volumetric flow rate Out put: Out put: moody friction factor, flow type, Reynolds number, relative roughness

4. What's the Advantage? Used in many ME classes, or for any application in which you need the moody friction factor head loss etc. Used in many ME classes, or for any application in which you need the moody friction factor head loss etc. Don’t have to Don’t have to read off of a read off of a complicated complicated chart. chart. Probability of Probability of error is error is decreased. decreased.
