If we have a pipe contains water and has friction losses of 1 bar ,, static head 2 bars ,, and it is open at its ending to atm.pressure ,, now we need the pressure at the pipe exit to be 2 bars ,, so we get a pump at rated head equals 5 bars at the required flow rate ,, now when we install the pump , i know that it responds to the system resistance which in our case is 1 bar of friction and 2 bars of static head so it reachs the exit at atm.preaaure ,, so how can we get the water at the exit at 2 bars ? i got confused
