The operational amplifier is a DC amplifier with a large negative gain factor, very high input resistance and very high output resistance. The operational amplifier always operates on the principle of

Functional construction of a control consisting of various modules or groups, including their connections.

The pressure drop Δp at a fitting (elbow, ankle fitting etc.) is calculated from the flow Q, the diameter of the orifice d, the density of the media and the back pressure coefficient ξ. The back press
