What is the classification of orifices according to their form, dimensions, and nature of the walls?
a) Form: circular, rectangular, etc. Dimensions: small or large. Nature of the walls: thin-walled and thick-walled orifices.
b) Form: circular, rectangular, etc. Dimensions: small or large. Nature of the walls: orifices in thin-walled and thick-walled containers.
c) Form: circular, rectangular, etc. Dimensions: small or large. Nature of the walls: orifices in thin-walled and thick-walled containers. The small orifices are much smaller than the depth in which they are found - the vertical dimension is equal to or less than 1/3 of the depth.
I - The small orifices with an area smaller than 1/10 of the container surface can disregard the liquid's v1.
II - The orifice is considered open in a thin-walled or sharp edge when the liquid vein is only in contact with the inner edge of the orifice.
III - If the value of e is between 2 and 3 times the diameter d, it is a nozzle.
IV - The coefficient is the ratio between the contracted section area A2 and the orifice area A.
a) I, II, III, and IV are correct.
b) Only I, II, and IV are correct.
c) Only II, III, and IV are correct.
d) Only I, II, and III are correct.
