There is also a suction side head that can be measured by a vacuum gauge.
WebTotal Dynamic Head (TDH) Calculator Total Dynamic Head (TDH) Calculator *Disclaimer: calculated values are preliminary steps and do not suggest your actual pump selection. See the model number guide or browse our product pages to find a series of pumps that will suit your needs. WebPump Power P (HP) = q (m3/hr) x ρ (kg/m3) x g (m2/s) x h (m) x p (Pa) / 2685600. Also above pump power is required to lift the liquid to head meters. But for calculating the net suitable motor, you need to calculate the shaft power of the pump. The shaft power is equal to the pump required power divided by the efficiency. P (kW -Shaft) = P (kW ...
WebThe shaft power of the pump (kw) = water delivery (l/sec) × head (m) / 102 × efficiency = flow × head × density × acceleration of gravity. 102 is the unit finishing constant. Water … WebYou will also learn how to determine the pump curve, calculate the net positive suction head (NPSH), and select the best pump type for your specific application. In addition, you will explore the different types of pumps, such as centrifugal pumps and positive displacement pumps, and the benefits and drawbacks of each.
WebThe relevant formula for establishing the flow rate of a specific centrifugal pump when impeller diameter is constant is expressed as: Q₁/Q₂ = (N₁/N₂) Where Q = flow rate, N = shaft speed, 1 = current or before, and 2 = new or after. By using this formula, we can determine how the flow rate varies when changes are made to the shaft speed.
