## Theory behind the Flowing fluid inside the pipe

## Theory behind the Flowing fluid inside the pipe

(OP)

pls, apology me to ask this kind of basic questions.

iam confused my self again..

When the water flowing inside the pipe what will be the pressure exerted by the flowing fluid?

I have known values of Size of the pipe, volumetric flow rate and Velocity of the fluid.

by using these values can I find the Pressure of the fluid, without consideration of the pump pressure?

If this is what you are looking for, Google Darcy Weisbach , and Colebrook White formula.

But I am not asking pressure loss due to friction inside the pipe. This I can find using the Pipe sizer and some other formule.

what I want is the pressure developed due to the motion of the fluid (Velocity).

that is I found now that is Velocity head = V2/2g.

is this correct?

p(rho) as density, a Pitot tube would measure total local pressure or stagnation pressure p_{stag}=p+1/2pv^{2}, while a static gage would measure p. The difference of the readings is the velocity head. The units in this equation can be Pa or N/m^{2}.
