Diana Fletcher Bilateral Tolerance
Bilateral tolerance is one of the primary three tolerances that occur most often on working drawings. A bilateral tolerance exists when a variation from the desired dimension is shown as occurring…
Sarah DeGuzman Flash Chamber
A flash chamber is a device that separates liquid and vapor refrigerant. It fits into the line after the expansion chamber, sending only liquid refrigerant to the evaporator and vapor…
Ejector vs. Eductor – Differences, Applications, & Alternatives
Ejectors and eductors are liquid jet pumps that use water or other liquids or gas under pressure to create a pumping action. Operators frequently confuse ejector vs. eductor pumps due…
Venturi Meter vs. Orifice Meter – Differences, Applications, & Alternatives
Venturi and orifice meters are devices that reduce the pressure of a moving stream to measure its average velocity, volumetric flow rate, or mass flow rate. The continuity equation and…
Running Torque – Definition, vs Holding, Prevailing, Breakway Torque
Running torque refers to the amount of torque a device needs to maintain the constant angular velocity of a rotating part once in operation. Knowing this value provides important operating…
David Etukudo Vortex Breaker – Formation, Effects on Flow, Design, and Applications
A vortex refers to the rotation of a fluid’s core while draining from a vessel. Moreover, engineers use vortex breakers to prevent the formation of vortices due to their effect…
Vacuum Pump Oil – Function, Properties, and Maintenance
Vacuum pumps change the pressure in a contained area to create a full or partial vacuum. The multifunctional element inside the vacuum pump that lubricates the pumping apparatus is vacuum…
Positive Displacement Pump – Working Principles, Examples
A positive displacement (PD) pump transports fluid through a system by periodically enclosing a set volume of fluid and moving it mechanically. Pistons, screws, gears, rollers, diaphragms, and vanes can…
Do Electric Cars Have Gears?
Electric cars generally do not have gears as they don’t have multi-speed transmissions. Electric vehicles receive power via an electric motor. The electric motor produces a consistent amount of torque…
