WebUsing the Energy Equation the head rise through a pump or fan can be expressed as: ha = (p2 - p1) / γ + (h2 - h1) + (v22 - v12) / 2 g (1) where ha = actual head rise (m fluid column) p = pressure (Pa, N/m2) h = elevation (m) γ = ρ g = specific weight of fluid (N/m3) v = velocity (m/s) ρ = density of fluid (kg/m3) WebCentrifugal pumps are used in series to overcome a larger system head loss than one pump can compensate for individually. As illustrated in Figure 13, two identical centrifugal pumps operating at the same speed with the …
