Part of the pressure change is due to elevation change and part is due to head loss associated
with frictional effects, which are given in terms of the friction factor f that depends on Reynolds
number and relative roughness f =j(Re,e /D).Part of the pressure change is due to elevation change and part is due to head loss associated
