Abstract
The validity of unsteady flow rate measurement with a plate orifice is examined for pulsating pipe flows and constant-acceleration pipe flows. The conventional steady state relationship between the flow rate and pressure loss through the orifice is applied to these kinds of unsteady flows. The flow rate thus measured is compared to that obtained by integrating the instantaneous velocity distribution over the pipe cross-section. The velocity distribution is measured by traversing a hot-wire probe. The two flow rates are in good agreement with each other.
