It depends on the pipe diameter and lesser on the pipe material (negligible).

without going into calculations, as a on-forward answer every 10 meters of pipe vertical elevation need 1 bar (14.7 psi) of water pressure to elevate.

the pressure drop is 

 

this equation is derived from the original Bernoulli formula

Delta P: pressure drop

L & D: Length of Diameter of pipe

Rho: density of fluid  ( for water = 1000 kg/m^3)

W: fluid velocity ( best between 1.2 m/s and 2.4 m/s to avoid water hammering and to keep it laminar flow)

Presure=weight/area pressure loss through piping for water. Pressure loss due to viscous effect Is proportional to lenght
