orifice size?

[fitter]

Apologies if this has been covered, I am a young fitter and new to this.

What is the orifice size that I would need to achieve 600LPM @ 200kPa using the K factor 42.43.

It is for a sprinkler head, using water, this is all the info I have

If you can post how this is calculated using the 'fluid flow calculators' please, that would be great

thanks in advance

Here is the text that is covering discharge through fittings:

This kind of calculation is not available in the moment, but will be in near future.
