It would take approximately 2 + 2= poo
Because it relies on the back pressure through a known orifice which its differential pressure across the plate relates to flow.
A restriction orifice (RO) is used to limit the flow through the pipe to a set flow by choking the flow at its sonic velocity. A flow orifice (FO) is usually used to determine the flow through the pipe from the pressure drop over the plate. There a normally two pressure taps (one on each side of the plate) and a pressure transmitter which determines the pressure drop over the plate. A formula is then used to convert this pressure drop to a flowrate for the specific fluid passing through the orifice. A FO usually has a temperature element to determine the gas temperature for use is the formula.
Orifice meter is a flow measuring device used for calculating the pressure drop,flow rate and behaviour of the fluid moving through the pipe.
Flow = Pressure / surface S = PI * ( Diameter / 2 ) ^ 2 now you can do the math... I can't tell with gallons, inch and psi.
The low pressure port of the A/C system usually has a blue or black dust cap and is located either on the larger diameter metal tubing typically found between the evaporator and compressor, on the compressor itself, or on the receiver drier (orifice tube systems only). The high pressure service port is found either on the smaller diameter tubing or the compressor and is larger in diameter. Only charge through the low pressure port.

A/C Orifice Tubes. The orifice tube acts as a small filter and restrictor inside the a/c system. The Freon gas passes through the small screen mesh of the tube and any debris (mostly metal shavings that come from normal wear and tear of the compressor) will get trapped, and the Freon gas will also be slowed down and restricted as it passes through the small opening of the orifice. There are different orifice tubes with different size openings/restrictions, and the color of the orifice can differentiate their diameter
yes, the pressure is directly related to the effective force acting on the fluid body, so from the pressure differential you can compute the effective force on a small mass of fluid in the orifice, which can then be translated into a flux integral, which can be solved for Volume/time.
