Dear experts among you, I work in a coking enterprise. The outlet pipeline of the pump (with water as the fluid) is not equipped with a flow meter; there is only a pressure gauge. How can I estimate the flow rate using this pressure gauge?
It’s not allowed, right? There is no inherent relationship between pressure and flow rate; high pressure can actually result in a lower flow rate.
I searched through books but couldn’t find any information on the relationship between flow and pressure
The flow rate at the rated value corresponding to the rated pressure, as indicated by the current, is the flow rate specified for the pump.
If necessary, consider using an external flow meter, and provide your parameters such as medium temperature, density, conductivity, pipe diameter, material, power supply method, and explosion protection rating. . .
Based on flow velocity V, pressure P, and pipe diameter D. Find the flow rate Qo
Using pressure to calculate flow rate is applicable to pipelines without pressure; it’s not possible to do so in pipelines under pressure. Your knowledge is mixed up
By finding the original manufacturer’s data for the pump and taking into account the actual production load at the installation site, it is possible to estimate the rated flow rate and normal flow rate.
