\n The amount of energy required to pump water depends on the volume of water pumped and head required is calculated by the formula:<\/span>

\n 600 m3 of water pumped daily into a water tank which is located 10 m above ground level.<\/span> Calculate how much energy is required?<\/span>
\n<\/a>
\n Using the above equation, the energy of water = (600 x 10) \/ 365 = 16.4 kWh per day.<\/span><\/p>\n
\n The term force or power is often confusing in the context of the energy terms.<\/span> The term is related but different meanings.<\/span> Energy is the capacity to do a job, while the power is the rate at which energy is used.<\/span> Force or power is the rate of energy use is usually measured in kilowatts (kW).<\/span> The power needed to pump water is called hydropower defined by the equation:<\/span>
\n<\/a><\/p>\n
\n Example:<\/span>
\n In the example above has been calculated that the energy required every day to lift up to 600 m3 of water up to 10 m is 16.4 kWh.<\/span> How hydroelectric necessary?<\/span> To calculate the water power of water takes energy needed for pumping:<\/span><\/p>\n\n
\n The energy required is the same for all three cases.<\/span> But energy depends on the rate of energy use.<\/span> The number of workers needed is greater if energy use shorter time.<\/span> Another way compute power and energy is to use pumped water discharge (of the volume of water pumped).<\/span>
\n Water Power (kW) = 9,81x Debit (m \/ sec) x Head (m)<\/strong><\/span>
\n Furthermore, the water energy can be calculated from water power by multiplying the operating time,<\/span>
\n Energy Water = Water Power (kW) x Operational time (hours)<\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
