Estimating circular pipe flow velocity through a known elevation profile and known length with a known initial pressure and flow velocity

I have a known elevation profile spanning the length of my pipe (~600 meters). An elevation value is given for every five meters of pipe. At the beginning of the pipe, I have a known velocity (1.1 m/s)...

Open-ended pipe under water, pressure vs. flow when pump starts up

A pipe with a pump and two open ends is placed under water. When the pump is initially turned on, will the pressure at P_out and P_in initially rise/fall, but then stabilize as a flow of water V_flux ...

Find pressure, given 2 velocities at open end of pipe and inside pipe, at different elevations

There is a tube travelling horizontally, 8m below the ground, with a diameter 15cm. It then turns upwards and at a height of 1.75m above the ground, it shoots water out with a velocity 32 m/s. Find ...
