thank a lot for your reply Stewartcs
if my system back pressure is about 2barG then, maximum flow rate will increased to be around 3100 lpm(9000 slpm) right?
(i've convert it from p1v1 = p2v2)
Hi Russ,thank for your reply
Did you mean this pump can move this amount of air with no pressure drop in the tank at that condition right?
The pressure in pipe system is around 2 barG.
So I have to select pressure and back-pressure regulator size and i just want to be sure that it can...
Hi all, i have to use an air pump to create a flow rate in a pipe system.
My pump model is hta100h-304 which i have attach the spec below.
From actual air delivery data(871.2lpm@10 kg/cm2G,762.3lpm@12kg/cm2G), i try to convert to mass flow rate unit and it is around 0.19 kg/s.
Is this mean...
hi all, I'm little confuse about the relation of these two equation.
is it right to say that Bernoulli's equation is just a case(incompressible,inviscid,steady) of navier stoke equation?
my problem can't use moody diagram directly because unknow of velocity and also Re.
but I've try the explicit equation from your link by substitute f and Re with the their velocity relation(f=121.067/v2 and Re=10765.5v from my previous calculation)to the equation and then trial and error to...
Another question, Is it ok to solve velocity from the set of equation in this document with known of pressure (dP) and pipe dimension (L, D)
I’ve done on calculation as attach below
Is it correct to use D-W and Colebrook this way?
thx a lot, Q_Goest
i think there is some conflict in unit of pressure in this document.
in eq 15, if i cancel g out(for my metric units calcuation like you've said)
the first term on the right hand side still not unit of height and the second term reduce to0.5v2 which is not unit of height...
hi Q_Goest thank for reply,
on pressure loss form(wiki),there is no g on the right hand side but it appear in equation 1 in pipe-flo pro document?
about equation 15, I'm confuse again because i solve there unit and the first term on the right hand side p/ρ is not unit of hieght ?
hi everyone this is my first thread on this board and sorry for any missing in English because it's not my native language
i just want to calculate the pressure drop base on pipe-flo pro document which has been share in this thread https://www.physicsforums.com/showthread.php?t=179830...
