The hydraulic gradient of a branch line can be calculated by taking the difference between the water pressure level at the node where the branch line starts (which is equal to the ground level at that node plus the service head) and the water pressure level at the end of the branch line (which is the sum of the ground level at the end point and the service head), and dividing this difference by (). The diameter of each pipe segment in the branch line is then determined based on the flow rate through that segment and the hydraulic gradient. a、Branch width b、Branch length c、Branch diameter d、Branch flow Rate Answer: b
