Hi all,
This is not homework, just theory discussion with my son.
My son has been asking some interesting questions with regard to displacement as it relates to water. All kinds of teenager, “what if” stuff. I have looked around for simple formulas, but I am not embarrassed to say, I do not know how to use them. I am just a simple machinist, with simple questions.
Can some one or a couple of people help us learn to use these formulas and what formulas we should be using?
For example:
P(HP) = M(Min) HG/33000 (1)
I know what each item stands for (I think) but I need an example of the formula executed with basic numbers so I can then use it.
P(HP) = Horsepower
M(Min) = Mass flow rate per minute
H= Head in ft (I think)
G= Acceleration of gravity or 32ft per sec squared.
This seems to me like a falling water equation of some type which I want to get data from.
The question, in basic terms, that we would like to know is: How much potential or stored energy (in watts/hp/) would a 55gal barrel full of air have if it was tethered to the sea floor at a depth of 500ft? It seems like a non liner question. As the displacement of water column pushed the barrel upward the water column pressure would be reduced as the column got shorter on it assent, correct?
Thanks for helping us have fun with physics,
SQ
