Instantaneous flows
NettetInstantaneous flow refers to a flow-rate measurement which may comprise a spot reading or an average rate of flow over a period of 15 minutes or less depending … NettetDynamic inflow. Calculating the induced velocities from the instantaneous flow is known as the equilibrium wake assumption, i.e the wake is assumed to react instantaneously to a change in the conditions.The induced velocities determined under the equilibrium wake assumption are known as the quasi-steady values, $\vec{v}\urm{q}$.

During this period, the instantaneous flow volume can be high …
NettetMaximum Instantaneous Flow means the maximum flow of Potable Water drawn, or Wastewater discharged, in litres per minute, at any given time, as further described in Schedule “F” and, for greater certainty, includes wet weather peak flow for Wastewater. At no point is this to exceed the design capacity of the accepting pipe. NettetThe record length and quality of instantaneous peak flows (IPFs) have a great influence on flood design, but these high resolution flow data are not always available. The primary aim of this study is to compare different strategies to derive frequency distributions of IPFs using the Hydrologiska Byråns Vattenbalansavdelning (HBV) hydrologic model.
