online_pipeflow_headloss:  Calculation of head loss in a pipe

Online discharge in a pipe

Online diameter in a pipe

V = Q/[(π/4) D2]

ν = f(T)

Re = V D/ν

f = 0.25 {log[(ks/D)/3.7 + 5.74/Re0.9]}-2

hf = f (L/D) V2/(2g)

[SI units: Q in m3/s; D in m; T in °C; h in m]
[U.S. units: Q in cfs; D in ft; T in °F; h in ft]
