Problem 1: A pipeline 300 m long discharge freely at a point 50 m lower than the water surface at intake (Figure 1). The pipe intake projects into the reservoir. The first 200 m is of 350 mm diameter and the remaining 100 m is of 250 mm diameter. (a) Find the rate of discharge assuming f= 0.06.

notes for the question and actual picture is the question thank you Although the following procedures are more or less sequential, be certain you read through and understand all the procedures and suggestions before you begin to actually construct a flow net. 1. Ensure that the use of a flow net is valid. (a) Flow is steady state. (b) Boundary conditions are known or can be approximated well. 2. Prepare for a trial-and-error solution: there is no unique solution. 3. Ensure that the boundaries of the flow field are drawn to scale. 4. Define the boundaries, and determine the nature of each boundary (a) equipotential, or constant-head, boundary (b) flow line, or no-flow, boundary: commonly an impermeable boundary (c) known-head boundary; commonly the water table (d) most often encountered, two equipotential boundaries and two flow line boundaries. 5. Determine the symmetry of the flow field, if any. This may reduce the work involved-for example, bilateral symmetry would require…
