How would I calculate the rate of ascent of an object traveling up through water using bouyancy as the propellant?
Example:
an open bottomed,8 cubic foot object at 197 ft deep with 1 cubic foot of air.
I know that the weight and shape of the object will affect it's rate of ascent. I also know...
I'm trying to find a formula that will determine what the volume of air is at varying pressures.
example: 1 cubic ft. of air at 100 psi
What would the volume be at 75 psi
at 50 psi etc.
Is there a formula that would make it easier to determine this??
If I have a tank of water 230 feet deep, and I have an open bottom barrel at the bottom that I want to fill with air, and I am pumping the air directly from the outside of the tank at the bottom (direct source of air so that I don't have to have 230' of hose to get to the bottom), I know that I...
I am trying to determine how long it would take to pump air into an open bottomed barrel(100 cubic feet) in a tank of water 230 feet deep. (Say a silo)
I know that the psi at that depth is approx 100 psi.
The pump will be located below the tank so there will be minimal amount of hose needed.
I...
I know that at 136 ft underwater, there is approx 100psi on an object. If it were a barrel with an open bottom, and I were pumping air into the barrel to push the water out, would I need 100 psi to do this? Or would the fact that the water would be escaping out the bottom reduce this?
In other...
