online_pipeflow_diameter:  Calculation of diameter in pipe flow

Online discharge in pipe flow

Online head loss in pipe flow

V = Q/[(π/4) D2]

ν = f(T) ; Re = V D/ν

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

D = fQ2 / [(π/4)2(2g)(hf/L)]1/5

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

[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]
