| Symbol | English | Metric |
| \(\large{ v }\) = velocity of fluid | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
| \(\large{ l }\) = length of tube | \(\large{ft}\) | \(\large{m}\) |
| \(\large{ p_i }\) = input pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ p_o }\) = output pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ r }\) = radius of tube | \(\large{in}\) | \(\large{mm}\) |
| \(\large{ \eta }\) (Greek symbol eta) = viscosity of fluid | \(\large{\frac{lbf - sec}{ft^2}}\) | \(\large{ Pa - s }\) |
