Quiz - Physics - Gauge Pressure

[Pedro Burrito]

From the PADI Dive Theory Exam:

What is the gauge pressure at 16 metres/53 feet of fresh water?

You will need to look at the constants to help with the answer: Constants Used For the Dive Theory Exam

I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.

Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.

Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.

tricky...

Thanks for the question

Slightly different terminology than I'm familiar with (had to check that) but I spotted the catch.

Hi @Pedro Burrito

Good question, half the early voters did not get one or both of the tricks

 

[HKGuns]

Now I’m curious if I got it correct. I guess my streak might be done.

For the record, I hate trick questions! Make me feel like an idiot when I slow down and re-read the question, lol.
Please keep the questions coming, this series is great!
Respectfully

Follow up question:
What depth will your typical depth gauge or computer read?

If you know what guage pressure is and roughly what an ATM is and that freshwater is less dense than salt water you can get the correct answer without the detailed arithmetic.

FWIW, there is an underlying assumption being made about the calibration of the pressure gauge being made that in the past could be made but now in our digital / customizable world can not.

I was wondering why they didn’t use the word SPG and had to google what a gauge pressure is.
