If I have a compressor delivering the compressed air at 8 bar. I am assuming this pressure would need to be regulated at some point. How do i do this? At 70 m depth 8 bar is required to overcome the static liquid head but as the buoy rises the pressure decreases and the pressure differential...
I was wondering if we could pump in a fixed volume of compressed air and since switch of the compressor. The air will expand as the buoy rises to the surface. So for example if you are at 70 m depth and you rise to the surface the pressure changes from 8 bar to 1 bar right so you have an...
This is basically a submerged buoy which has to be retrieved by blowing air into the 6 compartments completely filled with water to a total volume of 360 cubic meters. We would like to raise the buoy in about an hour. So the total flowrate of air has to be 360 m^3/hr. Water will be evacuated at...
How do I determine what flowrate of compressed air at fixed pressure is required to force a ballast tank full of water submerged at 70m with a volume of 60m^3. The outlet line size is 2inches for the water outlet and the air inlet is 1 inch. Please help if you can. The air will expand as the...
I need to determine the flowrate and line sizing for a submersible buoy operating using ballast tanks. The ballast tank initially contain trapped air and as the valves is open seawater rushes in to replace the air. This increases the density of the buoy and causes it to sink. How do I determine...
