A diaphragm type pressurizer on a domestic rainwater system, with the pump and Square D pressure switch in the background. A pressure tank or pressurizer is a type of hydraulic accumulator used in a piping system to maintain a desired pressure. Applications include buffering water pressure in homes. [1]
Hydraulic pressure switches have various uses in automobiles, for example, to warn if the engine's oil pressure falls below a safe level, or to control automatic transmission torque converter lock-up. Prior to the 1960s, a pressure switch was used in the hydraulic braking circuit to control power to the brake lights; more recent automobiles use ...
is the pressure, is the density, is the hydraulic diameter, is the frictional coefficient, is the axial coordinate in the manifold, ∆X = L/n. The n is the number of ports and L the length of the manifold (Fig. 2). This is fundamental of manifold and network models.
