Reynolds Number for Gas
Reynolds Number for Gas Formula |
||
| \(\large{ Re = 20,100 \; \frac{ SG \; Q }{ d \; \eta } }\) | ||
| Symbol | English | Metric |
| \(\large{ Re }\) = Reynolds number | \(\large{ dimensionless }\) | |
| \(\large{ Q }\) = flow rate of gas | \(\large{\frac{ft^3}{sec}}\) | \(\large{\frac{m^3}{s}}\) |
| \(\large{ SG }\) = gas specific gravity relative to water (water = 1) | \(\large{ dimensionless }\) | |
| \(\large{ d }\) = inside diameter of pipe | \(\large{ in}\) | \(\large{ mm }\) |
| \(\large{ \eta }\) (Greek symbol eta) = viscosity of gas | \(\large{\frac{lbf - sec}{ft^2}}\) | \(\large{Pa-s}\) |
