there is a reservoir 3 meter high full of water with continuous supply. said reservoir was tap with 3 inches diameter continuous pipe up to 4 kms, then extended it by 4 inches diameter pipe up to 20 kms. the initial discharge was 32gpm. the pressure read at 4km was 150 psi at elevation 50 meters and the pressure at 20kms is 215 psi. the difference in elevation is 168 meters. Is it possible to produce higher quantity of water at the end of 20 kms?

No, the discharge without head loss has to be the same. The larger pipe will have a lower velocity but the same discharge as the smaller pipe (again assuming no headloss).

A the volume flow rate of a piping system will be controlled by the smallest pipe in the system. If one section of the piping has a 3-inch diameter, adding a 4-inch diameter section will not increase the volume flow rate significantly.
