3.5.5 darcy_weisbach_q - Darcy-Weisbach volume flow Q
q = darcy_weisbach_q(p,d,fd)

Calculates the volume flow in a pipe using the Darcy-Weisbach equation.

Arguments

p

Pressure drop due to friction (kPa/km  ).

d

Pipe internal diameter D (m  ).

fd

Darcy friction factor fd .

Returns Volumetric flow rate Q (m3/h  ).
