It also has a throughput of 2000 litres per hour. I want to pump water up to my loft, which is approx 15m above the pump. What will the flow rate be at this height? Is it a linear... show more
I was was wondering how to calculate the head flow rate from a water pump. The water pump outputs 2 bar, which means that it will push water up to 20m in height. It also has a throughput of 2000 litres per hour. I want to pump water up to my loft, which is approx 15m above the pump. What will the flow rate be at this height? Is it a linear calculation of percentage of drop from maximum head height multiplied by the flow rate, (eg 5/20 * 2000 = 500 litres per hour?), or is it more complicated than that?
