During my parts chasing days of pre-mid 60'sfor my Dad and Uncles, all earning livings as automotive mechanics, used the term "Kit Set" which was sometimes shortened to just "Kit"
Then during my semi-retired years of the 90's, when doing fix-it-myself period, some parts young counter people...
Seems to me that part of the solution to the issue involves buoyancy.
Without any air vent holes, the device will float at some level in the water with water inside covered with a calculable volume of compressed air at a calculable pressure.
Now You will have a known gas pressure to start...
To get a pressure differential across the air holes, determining how small the air holes have to be to restrict the volume of flow of air to be less than the existing volume of water entering thru the 120 mm holes during a specific time period?

Ain't no way to ever get a pressure build up between flowing water and air caused by the orifice size stated above.

The last line failure occurred after volume input was causing the steel to yield as pressure/volume graph was being plotted.
Occurrence of this failure built my animosity against using gaseous substances for high pressure testing for safety reasoning. Scary length of noise and shaking during...
Yes, BigInch, it was in one section, but there was not any source of removing air except to run a pig between launcher and trap.
If You have access, write up of this was in 3 of the Oil and Gas Journal publications in the fall months of 1969 about a Transwestern Pipeline Company emergency...
Hydrostatic yield stress test on 11 miles of 20" OD pipe had a very minor difference in volume per stroke to make pressure rise each time a new test was done after repairing a piping defect found by testing..
Don't remember the difference and am too lazy to dig out 40 year old log books.
We...
When computers used trays of keyhole punch cards, locating access roads to proposed MCI microwave towers consisted of starting at top and locating road downward to desired existing access.

This is probably a simple hydraulics 101 problem but my 75 year old brain is totally blank on how to estimate the flow velocity of water given only the average slope of a river bed and average water depth.
Any suggestions using calculations with simple algebra formulas?

Consider the closure error is due to earth curvature imbalance of horizontal distances between vertical back sight and foresight.

If it is not invasive, what is the actual measurements of the 1:12 prototype?
Diameter?
Axis?
Foil Depth?
