This tool calculates pressure drop in a straight pipe due to flow of a non-Newtonian Bingham plastic fluid.

**Result**

**Reynold's Number**

Reynolds number for Bingham plastic fluid is defined as

\displaystyle \displaystyle Re = \frac{D.v.\rho}{\mu_{p}}

where, D is pipe inside diameter, V is fluid velocity, ρ is fluid density and μ_{p} is plastic viscosity.

**Friction Factor**

For Laminar flow, friction factor is provided by Buckingham Reiner equation.

For turbulent flow, an empirical relationship was developed by Darby and Melson.
