| Total Head Pressure Velocity Equations and Calculator |
| Liquid flowing in a conduit can undergo changes in energy form. Bernoulli’s theorem for an incompressible liquid states that in steady flow, without losses, the energy at any point in the conduit is the sum of the velocity head, pressure head, and elevation head and that this sum is constant along a streamline in the conduit. |

| Roller Chain Drive Design Calculator and Equations |
| Chain design is based on ensuring that the power transmission capacity is within limits for three modes of failure: fatigue, impact, and galling. Chains are designed so that the maximum tensile stress is below the fatigue endurance limit for the finite life of the material. |
