hi again ,
in selecting pipe size we put into consideration that velocity in pipe should be 0.75 m/s < v <3 m/s
so we try in the formulas above to find the appropriate size where the velocity is arround 1.5 m/s.
best regards,
chanel
hi ,
to calculate velocity u may use this eqation:
V(m/s)=Q/Pix(d^2)/4
Q=flow rate (l/s)
d=diameter or pipe in (m)
u may also see my attached file to calculate head losses and velocity using Darcy-weisbach.
hope that will be usefull .
looking for your forward.
best regards
Chanel...
