Calculating the radius of dish end size from the pressure vessel diameter is easy. All you have to do is add the blank radius by scaling the drawing from the side and you add five percent.

You wll also need to know its radius as well as its volume
Depends on the shape of the vessel. Different shape, different formula.
The water pressure depends only on the depth, not on the size or shape of the vessel. The pressure increases at about 1 atmosphere (or bar) every 10 meters.
Throw them all into a suitably sized measuring vessel marked with volumes and measure the amount of water they displace.
AnswerThe French catheter scale, also known as French gauge or Charriere (Ch) after the creator of the measurement scale, is commonly used in describing the diameter of medical devices/tubing. It was developed in the 1800's by a French surgical instruments maker, Joseph-Frederic-Benoit Charriere, to describe the circumference of medical tubing. The idea is that a non-circular tube will fit into the same incision or blood vessel as a round one. Therefore French size = 2*pi*r (where r is the radius in mm). Usually French size is considered to be 3 times the diameter in millimeters or 1Fr = 1/3mm.
