Concept explainers
(a)
The flow rate without diffuser.
Answer to Problem 6.99P
Explanation of Solution
Given information:
The pipe entrance is sharp edged.
The energy equation can be written as below for the system without the diffuser,
But, we can say,
Therefore, the above equation can be rewritten as,
Calculation:
According to the explanation given,
Assume,
Therefore,
Calculate the Reynolds’s number,
Calculate the friction factor,
Calculate the exact value of the velocity,
Calculate the flow rate,
Conclusion:
The flow rate is equal to
