Wheatstone Bridge

A Wheatstone bridge is a special type of electrical circuit that is used to accurately measure the unknown resistance of a component. It was also

laminar flow

Laminar Flow

Laminar flow is a phenomenon observed in flowing fluids that manifests during the study of fluid dynamics. In general, fluid flow can be described in

Kinematic Viscosity

In simplest terms, the viscosity of a fluid is the measurement of its resistance to deformation at a specified rate. For liquids, viscosity directly corresponds
