The flow rate in
Answer to Problem 6.116P
Explanation of Solution
Given information:
The pipes are made of asphalted cast iron.
The diameter of all pipes is equal to
The total pressure drop is equal to
The fluid is water at
The energy equation for the above system can be written as,
Since, the flow is parallel in pipe A and B, and the diameter is same for all pipes,
Calculation:
Assume, the water at
The roughness ratio is equal to,
According to the explanation, the energy equation will be,
Assume the friction factor as,
Similarly,
But, we know that,
By solving above equations,
Now find the Reynolds’s number and friction factor separately for each pipe
Replace friction factor in energy equation with above found friction factors,
Similarly,
Therefore, according to above equations,
The new velocities will be,
Therefore,
Calculate the flow rates,
Conclusion:
The flow rate in pipe A is equal to
The flow arte in pipe B is equal to
The flow arte in pipe C is equal to
