To get the hydraulic cylinder tonnage, divide the pound force by 2,000. I cannot reconcile this calculation back to either of the formulas you had. Solution: force = NOT CALCULATED. The density equation is: To solve the equation for Mass, rearrange the equation by multiplying both sides times Volume in order to isolate Mass, then plug in your known values (Density and Volume). ρ is the density of the fluid. In fluid mechanics, shear stress, defined as a tangential force per unit area, is used rather than force itself. As a result of this force, the piston on the right lifts a 10 pound weight a distance of 1 inch. Normal stresses are referred to as pressure p. Fluid flow will cause additional force, but at a flow rate of 3 feet per second, force due to flow is very small and can be neglected for most purposes. The sample calculation will show readers how to calculate the force of a linear actuator when it needs to thrust two hundred pounds of mass a full eight inches within a time limit of two seconds. Archimedes' Principle is that an object totally or partially immersed in a fluid (liquid or gas) is buoyed (lifted) up by a force equal to the weight of the fluid that is displaced. Fluid Viscosity Effects on Centrifugal Pumps hen sizing a pump for a new application or eval- uating the performance of an existing pump, it is often necessary to account for the effect of the pumped fluid's vis- cosity. 7 psi solely due to the change in elevation of the fluid as it flows uphill.
