An orifice is an opening or hole, whereas a lumen refers to the inner space or cavity within a tubular structure such as a blood vessel or intestine. In simpler terms, an orifice is an opening, while a lumen is the space inside that opening.

How do you calculate Orifice plate differential pressure?

To calculate the orifice plate differential pressure, you can use the Bernoulli's equation or the ISO 5167 standard equation. Measure the pressure upstream and downstream of the orifice plate using pressure gauges, then find the difference between these two pressures to determine the differential pressure across the orifice plate.

What is the difference between Restriction Orifice and Flow orifice or please explain the symbols RO Restriction orifice and FO Flow Orifice?

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.
