Two reservoirs are interconnected with a piping network as shown in Figure 3. Water is drawn off at B, C and D. Take only frictional head losses into account (the Fanning friction factors for each pipe are provided in table 1) and use the Hardy-Cross method to calculate the flow rate in each pipe. Show your calculations thoroughly for at least problem initialization (iteration 0) and the first iteration. Thereafter all other iterations may be in the form of a table. List the final flow rates.

Question
Transcribed Image Text:Two reservoirs are interconnected with a piping network as shown in Figure 3. Water is drawn
off at B, C and D. Take only frictional head losses into account (the Fanning friction factors
for each pipe are provided in table 1) and use the Hardy-Cross method to calculate the flow
rate in each pipe. Show your calculations thoroughly for at least problem initialization
(iteration 0) and the first iteration. Thereafter all other iterations may be in the form of a table.
List the final flow rates.
