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.

Electric Motor Efficiency Requirements under EPAct

Electric motor efficiency is a measure of how much input power a motor converts to torque and horsepower at the shaft. Efficiency is important to the operating cost of a motor and to overall energy use in our economy.

Straight Labyrinth Seal Flow Equation and Calculator

Straight Labyrinth Seal using Martin’s Equation and Calculator. Martin's equation is used for compressible flow with straight-through seals.

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.

Flat Belt Drive Design Calculator and Equations

Flat belts have high strength, can be used for large speed ratios (>8:1), have a low pulley cost, produce low noise levels, and are good at absorbing torsional vibration.
