I need to work out a flow rate of a fire hydrant in Liters per second.

I know the pressure is 3.5bar and the pipe diameter is 100mm

Any help would be appreciated

Thanks

Hello Dominic, welcome to PF :)

You might need a bit more information to get a sensible answer.

See e.g.__this calculator__ and what it all needs to calculate a pressure drop

My advice would be to read up a bit on fluid flow , e.g.__http://udel.edu/~inamdar/EGTE215/Laminar_turbulent.pdf [Broken]__
