A pipe having an internal diameter \(D\) is connected to another pipe of same size. Water flows into the second pipe through ' \(n\) ' holes, each of diameter \(d\). If the water in the first pipe has speed \(v\), the specd of water leaving the second pipe is
- A \(\frac{D^2 v}{n d^2}\)
- B \(\frac{D^2 v}{d^2}\)
- C \(\frac{n d^2 v}{D^2}\)
- D \(\frac{d^2 v}{\pi d^2}\)
Answer & Solution
Correct Answer
(A) \(\frac{D^2 v}{n d^2}\)
Step-by-step Solution
Detailed explanation
\(\pi\left(\frac{D}{2}\right)^2 X v=n\left(\frac{d}{2}\right)^2 X v^{\prime}, \quad v^{\prime}=\frac{D^2 v}{n d^2}\)
