Pressure washer vs. Regular sprayer

It always makes me cringe when ppl talk about spraying their hands with a pw. It only takes 100 psi to break the skin. I have seen painters with the spray guns that accidentally hit their palm not the wall and have paint ejected through the end of their thumb. It's a painful looking injury and water can easily do the same. So disclaimer stop putting your hand in front of a pw lol

100 psi might be a bit low...but I TOTALLY agree about not aiming a pressure washer at hands, feet, whatever... Injection wounds can be very serious. Many people get away with using the pressure washer to rinse of their feet... I don't plan on following their lead!
 
Personal preference, I would prefer pressure for doing chemical decon.

Less preference and more about efficiency, I find that I use roughly half the amount of water when using pressure washer vs conventional hose.

It def depends on the skin of the individual. But I have seen a low pressure paint system create a small pin hole on a palm but the thumb is blown out on the end of the hand. The paint went around the bone following the path of least resistance. He now is 2 fingers less of a left hand. Most of these injuries happen on the non dominant hand as well.

I agree I'm never hitting my feet with a pw either. They are made to blast things off the surface not a gentle scrub lol

Hose length, ID of pipe feeding garden outlet, hose ID, etc.....I think your meant GPH....
A wild guess is that it takes a bit less than a minute to fill up a 5 gallon bucket with my 3/4 50ft hose

The way you reference filling a 5 gallon bucket makes total sense but I did find this calculator.

http://irrigation.wsu.edu/Content/Calculators/Residential/Garden-Hose-Flow.php

A 5/8 50ft hose at 40 psi uses 22 GPM not GPH.

If you drop the length down to 25ft hose it jumps to 44GPM.

Not sure what the average supply pressure is for a household hose bib
Maybe I'm missing something. Maybe that's just an open hose with no nozzle.
