Pump Efficiency: Fluid power and useful work done by the pump divided by the power input in the pump shaft. 7. Energy Performance Assessment of Water Pumps Bureau of Energy Efficiency 100 7.4 Field Testing for Determination of Pump Efficiency To determine the pump efficiency, three key parameters are required: Flow, Head and Power.
Paper deals with calculation and design of the heat pumps that are used for purposes of heating and cooling. Heat pumps are systems that draw heat from one source (earth, water, air or ambient
Tie the other ends of the string together, fill the glass half full with water and hold it suspended from the strings. Start spinning. As you may have guessed, the fluid inside the glass will become pressurized. How do you know that the fluid is pressurized? To prove it to yourself, make a very small hole in the glass bottom.

3.3.1 Erosional Velocity formula used in Hydraulic calculation: (1) The velocity above which erosion may occur in gas/liquid two-phase flow can be determined using the following empirical equation. V e = C e /√ρ m, where, V e =Erosional velocity, ρ m =Homogeneous density, C e = Empirical constant normal in the range of 180-240.
Active power – power consumed by an electric motor that becomes useful work. Apparent power – sum of active and reactive powers or the product of current and voltage. Drinking water – colorless, tasteless, and odorless liquid found in nature or produced through a purification process; used for human and animal consumption.
Calculations of water pumping system design. A water pumping system pumps the groundwater to the surface for its usage.The pumping system requires two major components, mentioned below.. A water pump that has a motor in it for pumping purposes, and; A power source to run the water pump.; When a grid is present nearby, the power to run the water pumping system can be taken from the grid. Three important characteristics of a pump system: pressure, friction and flow 3. What is friction in a pump system 4. Energy and head in pump systems 5. Static head 6. Flow rate depends on elevation difference or static head 7. Flow rate depends on friction 8. How does a centrifugal pump produce pressure 9. What is total head
The effective power is: the product of the pump’s head, mass flow and gravitational acceleration. Formula for calculating flow of submersible pump: 60HZ flow×0.83=50HZ flow. 60HZ head×0.69=50HZ head. 60HZ power ÷ 1.728=50HZ motor power. Motor output power = Q (flow) × H (head) / 367.2 / efficiency × 1.15. Motor output power = shaft power

calculations we will use primarily Torr or atmospheres). 2. Volume: The internal capacity of a container, or vessel. (Liters) 3. Temperature: The temperature of a gas is a function of its kinetic energy, that is, how vigorously the gas atoms are vibrating. Temperature must be specified in terms of an absolute temperature scale.

2. Calculation of hydraulic and shaft power How to calculate the pump hydraulic power ? The hydraulic pump power calculation is done thanks to the pump flowrate, the pump head and the density of the fluid being pump. Pump power formula is the following : P hydraulic = Q.H.ρ/367. In case the density is changing significantly when the fluid goes through the pump, the density at the inlet is used.
