 `hQeps2fDRe` computes both the Darcy friction factor *f* and the Reynolds number *Re* given the head loss *h*, the pipe's length *L* and relative roughness *ε*, the volumetric flow rate *Q*, the gravitational acceleration *g*, and the fluid's density *ρ* and dynamic viscosity *μ*. Replacing hydraulic diameter *D* in the Darcy-Weisbach equation by the Reynolds number *Re*,

 Along with the Colebrook-White equation, this version of the Darcy-Weisbach equation produces a system of two equations with two variables. Solution is computed iteratively.
