Pump Power Pumps are usually driven by electric motors, diesel engines or steam turbines. Here you can calculate, how much water (or something else) a pump can handle theoretically. The direct heat loss from the overall surface area of the structure. For the phone version, When the pump duty is calculated, use the pump kPa (or start) pressure, (shown at the end of the page) as the 'Start pressure' to calculate the pipe sizes. Pressure gauges typically incorporate scaled measurements whereas pump performance is measured by its head – ie what height it can pump a fluid to. For the meaning of the variables see the nomenclature in table 20. Using the enthalpy equation we can calculate thermal energy and power for heating or cooling or calculate flow rate of fluid that is heated or cooled. Pump Efficiency Calculation.
