Regarding Ba products, issues with flow rate and density!
Thread Content
I have a fluid that is a gas mixture; its pressure is 0 KPa, the temperature ranges from 320 to 400°C, its density is approximately 0.6 KG/M3, and its flow rate is around 13 m/s. Using Anubaa, the pressure difference comes out to be only around 80 Pascals. Using a V-cone, the differential pressure value is also very small. For ordinary differential pressure flow meters, measurement is possible at gas flow speeds of around 3–4 M/S; however, with a flow speed of 13 M/S as in this case, measurement is indeed not feasible. I’ve wondered whether it has something to do with density – for example, hydrogen flow meters require very high flow rates in order to function, and the same is true for ammonia and helium. Since all three of these media are lighter than air, can it be said that gases with a lower density than air are not suitable for use in differential pressure flow meters when the gas flow velocity is in the range of 3–4 M/S? Can someone answer?
The Reynolds number = pipe diameter * flow velocity * fluid density / fluid viscosity. Of course, it is related to density; when dealing with flow rates, it’s essential to know what the Reynolds number is, as it is very useful for selection and application purposes
