In fluid dynamics, Bernoulli's principle states that for an in viscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.

Used as auxiliary connection through which the fire department can pump water to suppler existing water supplies

It allows flow in one direction and prevents backward flow and with this given signal to BMS alarms

When we speak of the efficiency of any machine, we are simply referring to how well it can convert one form of energy to another. If one unit of energy is supplied to a machine and its output, in the same units of measure, is one-half unit, its efficiency is 50 percent. The overall efficiency of a centrifugal pump is simply the ratio of the water (output) power to the shaft (input) power and is illustrated by the equation below:
Ef = PW / PS
Where:
Ef= efficiency
Pw= the water power Ps= the shaft power
