I will stay with Hydro values and general accuracy The basic hydro formula is Vel= square-root( 2*G*H)
G= gravity=9.81 H= Head = meters 1 bar = 14.7 psi H= psi/1.42 = 14.7/1.42=10.35 meters 1 bar H= 10.35 meters VEL1= 14.25 meter/sec = 1425 cm/ 2 bar H= 20.7 meters VEL2= 20.15 m/s = 2015 cm/s 3 bar H= 31.056 meters VEL3= 24.68 m/s = 2468 cm/s 4 bar H= 41.41 meters VEL4= 28.5 m/s = 2850 cm/s 32 mm= 3.2 cm pipe diameter PA = pipe area = PI * Radius^2 = 3.14 * (3.2cm/2)^2= 8.043 cm^2 VOL(x)= VEL(x) * PA = cm^3/sec V(l/m) = Volume ( liter/minute) V(l/m) =VOL(x)* 60 SEC / 1000 = Liter/minute VOL1(l/m)= 8.043 * 1425* 60 SEC / 1000 = 687.676 l/minute I think that you could do the last 3 bars.
