So if I have a pipe and I split it into 3 pipes what will the pressure on the ends of this 3 pipes be ?

Is p0 = p1+p2+p3 ?

P1,p2,p3 = pressure at the ends of the 3 pipe

P0 = pressure before splitting into 3 pipes.

From what I have been reading p0=p1=p2=p3 . If so how can I reduce the pressure and increase flow rate at the ends of the 3 pipes?

The same. With that information.

No.

Decrease the diameters of P1, P2 and P3.

Decreasing the diameter, increases the velocity.

Increasing the velocity, decreases the pressure.

Fluid flow flow is a science itself. It has to be analyzed as a system, with the appropriate parameters.

You might find better luck on a steam or pumping forum.

If you mean the ends remote from the splitting point, the pressure will be less than P0 if there is flow. Pressure drop is proportional to flow rate (and vice versa) if the fluid in the pipe is incompressible.
