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.

Blood pressure increases if the diameter of the blood vessel decreases.
To calculate the weight of an empty pressure vessel, you can determine the volume of the vessel and then multiply it by the density of the material from which the vessel is made. This will give you the mass of the vessel, which you can then convert to weight by multiplying it by the acceleration due to gravity.

An increase in blood flow can cause vasodilation of the radius vessels, leading to an increase in their diameter. This allows for more blood to flow through the vessels, which can help improve tissue perfusion and oxygen delivery to the surrounding tissues. Conversely, a decrease in blood flow can lead to vasoconstriction of the radius vessels, reducing their diameter and potentially compromising blood flow to the tissues.
The dish end formula is used to calculate the dimensions of a dish end or dished head, which is a type of pressure vessel closure. The formula helps determine the shape and dimensions of the dish end based on factors such as diameter, knuckle radius, and height. It is commonly used in engineering and manufacturing industries for designing pressure vessels.
Use the analogy of a hose. When the pressure is high a small bore hose will act to limit the flow but at a lower pressure the radius is hardly a factor. So arteries which have a much higher pressure are more affected by radius than lower pressure than the low pressure venous system.
Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
Blood Pressure can be affected by all three factors. If the vessel diameter increases (vasodilation) Blood Pressure can be lowered. Blood Viscosity can also have an affect on blood pressure, the more viscous (thicker) the blood is, the slower it will flow through the body. Finally, irregular surfaces of the blood vessel wall can cause them to catch or become stuck, which ultimately slows blood flow, reducing blood pressure!
To calculate the amount of gas required to raise the pressure of a closed vessel to a known value, you can use the ideal gas law equation: PV = nRT. Plug in the initial pressure, volume, and temperature of the closed vessel, as well as the known final pressure. Then solve for the number of moles of gas (n) needed to reach the desired pressure.
