COMPRESSIBILITY OF A FLUID C() = 1/BM SPECIFIC GRAVITY OF A FLUID SG = W/62.4283 VALVE (Cv) FLOW FACTOR Cv = (Q SG)/( p ) VISCOSITY IN CENTISTOKES For Viscosities of 32 to 100 Saybolt Universal Seconds: CS = .2253 SUS - (194.4/SUS) For Viscosities of 100 to 240 Saybolt Universal Seconds: CS = .2193 SUS - (134.6/SUS) For Viscosities greater than 240 Saybolt Universal Seconds: CS = SUS/4.635 Note: Saybolt Universal Seconds can also be abbreviated as SUS. Pressure = Force (Pounds) Unit Area (Square Inches) Flow Rate = Volume (Gallons) Unit Time (Minute) Horsepower = Pressure (psi) x Flow (GPM) 1714 Velocity = .3208 x Flow Rate through I.D. (GPM) Internal Area (Square Inches) Additional Volume = Pressure (psi) x Volume of Oil under Pressure 250,000 (approx.) Compressibility = 1 Bulk Modulus of the Fluid Specific Gravity = Weight of One Cubic Foot of Fluid Weight of One Cubic Foot of Water Valve Factor = Flow Rate (GPM) Specific Gravity Pressure Drop (psi) Centistokes = .2253 x SUS - 194.4 SUS ( ) Centistokes = .2193 x SUS - 134.6 SUS ( ) Centistokes = SUS 4.635 ( ) Fluid Power Formulas
