Date Issued:2015-05
Abstract
Lifting and moving water around farms with pumping systems for irrigation consumes plenty of energy as water is a heavy liquid. Every litre of water has a mass of one kilogram. A cubic metre of water has a mass of 1000 kg, or a tonne, and a volume of 1000 litres. A Megalitre (ML) has a mass of one million kilograms or one thousand tonnes.
