Question

Part 3: the velocity within the pipe should be between 0.95 and 1.52 m/s

A) For the distribution network: -The pipes in the network are cast iron with a roughness height (e )= 0.26 mm-Acceptable ΔQ =∓0.0005 m3/s -Assume initial velocity within the range between the minimum and maximum values.

B) The discharge pipe for the excess flow in the network has an open-end discharging to the natural stream.

3. Designing and evaluating the pipe network and a pumping system used to distribute water at two facilities downstream from the reservoir. (Fig. 2 and Fig. 3) Two vacation facilities consisting of multi-story buildings will be constructed 800 m downstream from the reservoir. These facilities will be located directly across the valley from each other at the highest elevation on either side of the valley (see Fig .3 below). Knowing that the inflow rate for each facility is 45 L/s, and to be distributed at the entrance junction as illustrated in Fig. 3.. Table 1. Building height above ground level and water demand.
