Calculation of steam leakage flow rate through small holes
Thread Content
I would like to ask the experts: what formula can be used to calculate the flow rate of steam leaking through a small hole? Or are there any reference materials I can consult? Assume that the small hole is a smooth circular hole. Diameter of 1mm
If it can be calculated in this way, then what’s the use of the measuring element (throttle element) in the flow meter? It can be measured simply by using a small hole.
The original device is used to measure flow rate in pipes, while mine measures the flow rate that leaks out through small holes into the external atmospheric pressure – the two are not the same
Once the pressure difference before and after is known, it can be calculated; the principle is the same as that of an orifice plate
I did some research, and they seem to be different: one is a pipeline leak, while the other is flow measurement within the pipeline
To determine whether the speed of sound has been reached, one needs to know what the pressure difference is.
Thank you. I found a calculation table online; it’s very convenient for calculations – first determine the speed of sound, and then carry out the calculations
Could the original poster provide a website address? I also need to do similar calculations
