The slurry pump head is stands for the effective energy gained of the liquid from pump inlet to outlet, so the effective power for the liquid gained is head multiplied by mass flow and acceleration of gravity – the slurry pump effective power : Pe = ρgQH (W) = γQH (W)
ρ – density of the liquid pumped (kg/m3);
γ – pumping liquid severe (N/m3);
Q – pump flow (m3 / s);
H – pump head (m);
g – acceleration due to gravity (m/s2).
