Thanks for your reply, do I have this right ?
delta P would be:
system pressure at or just before the nozzle - (for the sake of ease at the moment) atmospheric pressure
which would be 1.52bar but in SI
so SqRt (P / (0.5*density)) would give v
so
v = SqRt (152000 / (0.5*1000))
=17.43...
Hi all,
my first post on here and just wanted to check something I'm working on for a project.
The project is to use a pump to create a jet of water to manouvre small boat.
I have found a formula to work out the jet reaction force in a fire fighting textbook which gives:
R = 0.157 * P * d^2...
