Nothing compared to elevation

Forgive me if I’m wrong, but since they’re using hose and not pumping up a standpipe, isn’t the pressure loss per hydraulic length more than the pressure loss due to elevation?

Assuming they’re using a smaller diameter hose, considering the drone has to lift the hose plus the water in it.

Sorry, I’m new to pumping and any explanation would be appreciated!

You need to overcome both those issues. I’d be curious how many gpm they’re getting out of that setup.
