11. Thus variable geometry turbomachine offer a better match of efficiency with changing flow conditions . 12. At a Spring Brook during high flow conditions . 13. In the headwaters upstream of Otorohanga the river can be very clear during low flow conditions . 14. Under normal flow conditions the water will spill over the fuse plug and down the spillway. 15. :A term used to describe the flow condition where fluid flow becomes chaotic and disordered. 16. However, the stream only significantly affects the water quality of Heberly Run during high flow conditions . 17. In low-flow conditions , its flow ranges from 0 to 38 cubic feet per second. 18. The flow conditions must have a sufficiently small value of Reynolds number for there to be laminar flow. 19. Variable geometry of the wicket gate and turbine blades allow efficient operation for a range of flow conditions . 20. The wave operator of Lighthill's analogy is limited to constant flow conditions outside the source zone.
