Hello,

I wonder if someone could assist me with a problem ?

I want to know the pressure inside a pipe at a particular point.

Pipe details: 15mm
Fluid: water
Flow rate: 9 l/m

Would more information be required do you think ? Formula could I use ?

Regards,
Justin

Use Bernoulli's equation. You will have to know the pressure at some other point (like atmospheric pressure at the discharge or X psig at some pressure guage). You'll also need the physical properties of water at the operating temperature, the roughness of the pipe, length of pipe from the reference point to the point of interest, fittings, and elevations. Is 15 mm the inside diameter? That's what you'll need.
