About This Product
Bernoulli's equation expresses conservation of mechanical energy per unit volume for steady, incompressible, non-viscous flow along a streamline. Where height stays about the same, an increase in flow speed corresponds to a fall in static pressure. With the apparatus on a level surface and its fluid source connected as instructed, students start the flow and compare pressures at different points along the flow section.
Frequently Asked Questions
Q1. What happens to pressure when flow speeds up? At roughly the same elevation, an increase in flow velocity corresponds to a reduction in static pressure, as Bernoulli's equation describes for ideal flow.
