Flow rate area velocity
WebJun 13, 2024 · Streamgaging generally involves 3 steps: 1. Measuring stream stage —obtaining a continuous record of stage—the height of the water surface at a location along a stream or river. 2. The discharge measurement —obtaining periodic measurements of discharge (the quantity of water passing a location along a stream) 3. WebThe greater the velocity of the water, the greater the flow rate of the river. But flow rate also depends on the size of the river. A rapid mountain stream carries far less water than the Amazon River in Brazil, for example. The precise relationship between flow rate Q Q size 12{Q} {} and velocity v ¯ v ¯ size 12{ {overline {v}} } {} is
