Unformatted text preview: per second is or 0.25CFS b. It is important to measure the flow rate at precise locations in both pipe and channel cross sections because with the flow rate on hand, a farmer or irrigator can calculate how much water will deliver to their crop in a given time. It is important to be precise because a small field error can lead to a large miscalculation in the long run, which will cost somebody their money. c. A potential source of error in the measuring of the pipe is the convoluted path that the water takes to get through the pipe; going through bends and valves. This alters the velocity of the water coming out, which ends up skewing the calculated flow rate away from the actual flow rate. Also, as the water comes out of the pipe, there are pockets of air in the stream coming out of the pipe. The actual diameter of the pipe is not accurate in this case....
