Thank you sir for this useful lesson. Which procedure is valid for PIPE TAPS?
@RDCINST2 жыл бұрын
You can use this procedure for sizing with pipe taps, but you will need the correct discharge coefficient (C) for the pipe taps. In this video I use the discharge coefficient calculation for flange taps. You can see this at 13:00. The Flow Measurement Engineering Handbook has the formulas for calculating other discharge coefficients on page 9.13 and table 9.1.

Orifice sizing is based on normal flow or the maximum flow?
@RDCINST2 жыл бұрын
Start with the maximum flow and multiply it by 0.8 to get the normal flow. 80% of maximum flow is considered to be the normal flow. If you size based on the normal flow you can skip that step, but keep in mind a large increase in flow will be above the range. For the best measurement accuracy, the normal flow should be at 80% of the range.

@@RDCINST Thank you. Also wanted to know if there are limitations to using this method to size an orifice. how large of a differential pressure can I size an orifice for? A few references mentuon that when dealing with gases, this method is not suitable if ratio of downstream pressure to upstream pressure (@ the taps) is greater than 0.75. Is that the case here?
@RDCINST3 жыл бұрын
@@wasteurtime5677 refer to page 9.54 of the reference. It’s pretty standard to size the maximum flow to produce 100”H20 or 25 kPa. This is a standard range for the device used for measuring differential pressure. I have seen some flow computers that have a maximum range of about 65 kPa, so it would be important to know that maximum range for the device measuring differential pressure. The reference says to limit the ratio of differential pressure over static line pressure to less than or equal to 0.04 for gases.

@@RDCINST How to reduce permanent pressure loss?
@RDCINST3 жыл бұрын
@@RathodRidesRonin you can’t avoid the permanent pressure drop due to an Orifice. A common differential pressure range used for sizing an Orifice meter is 0-100 “H2O. This means the pressure drop should never be more than 100 “H2O. If this is too much, consider using a Venturi tube over a Orifice meter. It produces a lower permanent pressure drop.
