3) A pipe grid system is advantageous when compared to a dentritic system because:a) a grid is easier to analyzeb) a dentritic system is inherently unstable when searching for flow solutions✓a grid system reduces the impact of customers during pipe failured)a grid system is more efficient because it reduces flow losses while delivering the sameflow volumes

Here's an explanation for each option: a) "A grid is easier to analyze" - This is not necessarily…

While planning a future expansion, a water distribution pipe will be replaced as shown in Figure 2. The current plan is for the new configuration to have the same head-loss between points A and B once the new pipes are laid. Considering that the physical characteristics of these new pipes will be identical to the previously laid pipe (L, D, CHW), (A) what will the new operational flow be? After years of wear and tear while operating above the required flow, the pipes have prematurely degraded. The Hazen-Williams coefficients have dropped to: CHW₁= 130, CHW2= 135, CHW3= 125. You must now (B) quantify the head-loss between points A and B for an operational flow of 200 l/s.

After initial mixing, the dissolved oxygen concentration in the river is 9.5 mg/L, and the temperature is 20°C. The ultimate BOD of the mixed river water is 30 mg/L, the rate constant for BOD at 20°C is 0.48 di and the re-aeration constant at the same temperature is 0.72 d.
