How to Calculate the Volume of a Cylinder

Formula: Volume = π x r² x h Where:π = Pi = 3.14159r = Radius = 1/2 Diameterh = Height ExampleYou have a cylinder with a 5 inch diameter and it’s 6 inches high. What is the volume of this cylinder? (5 Inch Diameter Divided by 2) = 2.5 Inch Radius2.5 Inch Radius × 2.5 Inch Radius = 6.256.25 […]

How to Calculate Maximum Plunger Diameter

Formula: DP = 2 × √{FL / (P × π)} Where: DP = Maximum Diameter of Plunger in inchesFL = Rod Load Rating in poundsP = Operating Pressure in pounds per square inchπ = Pi = 3.14159 Maximum Diameter of Plunger [in] = 2 × √{Rod Load [lbs] / (Operating Pressure [PSI] × 3.14159)} Example:Rod Load Rating = 10,000 PSIOperating […]

How to Calculate Maximum Operating Pressure from Rod Load

Formula:PMAX = FRL × 4 / (DP2 × π) Where: PMAX = Maximum Operating Pressure* in pounds per square inchFRL = Rated Maximum Rod Load in poundsDP = Plunger Diameter in inchesπ = Pi = 3.14159 Maximum Operating Pressure [PSI] = Rated Rod Load [lbs] × 4 / {(Plunger Diameter [in])2 × 3.14159} Example:Rated Rod Load = 10,000 lbsPlunger Diameter = 6.5 […]
