The discharge<span> of a stream is the product of its velocity </span><span>(V </span>- length of travel per unit of time such as feet/second) times depth of the water (D<span> - unit of length) times width (</span>W of the water<span>- units of length). (Make sure all all three lengths are expressed in the same unit.)</span><span><span>
Discharge = V x D x W</span>If length is measured in feet and time in seconds, Discharge has units of <span>feet3/sec</span> or cubic feet per second (cfs).Depth times Width gives the cross-sectional area. The shape of the channel is important because of the reduction in velocity due to friction along the channel margins. In a natural situation, an increase in discharge (cubic feet/second) will result in an increase in all three parameters - the river becomes wider, deeper and flows at a higher velocity.</span>
Answer:
i believe the answer is C
Explanation:
For a free market economy, having no external regulation over the prices and production of goods (in terms of amount of goods) other than those exhibited by the market itself is usually considered to be the main characteristic.
