Nozzle water demand Water demand is how much water a nozzle requires to achieve the objective. Although there are many types of fountain nozzle each water demand is different. Lets us compare the komet 3-5T and Schaumsprudler 35-10e
In order for the komet nozzle shown to have a jet that reaches 50cm it requires 3.8 litres per minute,@ 0.07 bar pressure. This is called its "water demand" Any less and it will not be able to have a jet height of 50cm Similarly our most popular foaming nozzle the Schaumsprudler 35-10 e requires 55 litres / minute @ 0.14 bar to achieve a height of 50cm The same is also true of any other nozzle, in that each has its own water demand, regardless of what "pattern" it has. If The pump you are considering using can not meet the water demand of a nozzle, then that nozzle will not give the pattern / height you will be expecting. Similarly if you have multiple nozzles, the water demand of all nozzles must be added to give the total water demand, and the pumps and pipes sized accordingly. |
