How do you calculate flow from a pressure measurement?

WebFor example, at an input signal pressure of 6 PSI (25%), the output signal percentage will be the square root of 25%, which is 50% (0.5 = √0.25) or 9 PSI as a pneumatic signal. At an input signal pressure of 10 PSI (58.33%), the output signal percentage will be 76.38%, because 0.7638 = √0.5833, yielding an output signal pressure of 12.17 PSI. WebMar 17, 2016 · Assuming the pipe is $5\, m$ long and that the $3 \, bar$ pressure is the gauge pressure, the flow rate is $$ Q = \frac{\pi (0.015)^4(3\times 10^5\,Pa)}{128(8.9\times 10^{-4} \, Pa\cdot s)(5\,m)}=0.0084 \frac{m^3}{s} = 8.4 \frac{l}{s} $$ However, if we calculate the Reynolds number for this flow rate: WebCalculators for pressure differential devices Calculator's features: Calculate flow rate in pipe based on the created pressure drop, For liquids and perfect gases, Flow velocity calculation, Convert between volume and mass flow rate, Reynolds number calculation, Discharge coefficient calculation. east tool radiation
