| Hydraulic Fluid Formulas For: | Word Formula | Letter Formula |
| Velocity Through Piping In Feet/Second Velocity |
Velocity = |
V =  |
| Compressibility of Oil In Additional Required Oil To Reach Pressure |
Additional = Volume |
VA =  * Approximately 1/2 % per 100 psi |
| Compressibility of a Fluid | Compressibility = |
C(ß)= |
| Specific Gravity of a Fluid | Specific = Gravity |
SG = |
| Valve (Cv) Flow Factor | Valve Factor (Cv) = |
Cv =  |
| Viscosity in Centistokes | For Viscosities of 32 to 100 Saybolt Universal Seconds: Centistokes = .2253 x SUS –  |
CS = .2253 SUS – |
| Viscosity in Centistokes | For Viscosities of 100 to 240 Saybolt Universal Seconds: Centistokes = .2193 x SUS –  |
CS = .2193 SUS – |
| Viscosity in Centistokes | For Viscosities Greater Than 240 Saybolt Universal Seconds: Centistokes =  |
CS = |
