im just trying to evaluate the difference between having a 10 or 20 in diameter header.
the first set up was 10 inches diameter header and it was changed to 20 inches due to unknown reasons.
i just want to know if that change actually help in terms of the discharge pressure.
thank...
kindly help me with this one.
im trying to find out what is the effect if i increase the diameter of my header pipe in a water distribution line.
i think pressure at the discharge pipe will decrease. if so, i don't know how to justify it.
tnx in advans.
so i need to compute the flowrate using bernoulli taking into account % opening of the valve in the friction loss term?
if so, where can i find values of Kf for both ball and butterfly valves..
tnx a lot..
is it right to say that valve opening for both ball & butterfly valve is directly proportional to flowrate passing through it?
say 100 m^3/hr at 100% opening
50 m^3/hr at 50% opening??
thanks in advance..
its a PD pump and that's the only data available for that pump since its old already.
so far here is what i did with my problem;
to solve for Q in lines 1 & 2, i first computed for Pressure at point B (pls refer to attached drawing) using bernoulli's equation in pipe A-B using 30 meters...
kindly help me with this one..
i want to compute the actual volumetric flowrate in line 1 & 2. discharge for both lines are in different elevations. given data for me is these;
mono pump capacity= 10 m3/hr at 30 meters
line 1 from tee to discharge is a 2-inch pipe
line 1 discharge...
