Nozzle water demand

Nozzle 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 differnt. Lets us compare the komet 3-5 and Schaumsprudler 35-10e

 

 

 

Komet 3-5T nozzle   Schaumsprudler 35-10e nozzle

 

 

  Here they are side by side for comparison

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.
