Two water pipes of diameter \(2 \mathrm{~cm}\) and \(4 \mathrm{~cm}\) are separately connected to a main supply line. The velocity of flow of water in the pipe of \(2 \mathrm{~cm}\) diameter is
- A 4 times that in the other pipe
- B \(\frac{1}{4}\) times that in the other pipe
- C 2 times that in the other pipe
- D \(\frac{1}{2}\) times that in the other pipe
Answer & Solution
Correct Answer
(A) 4 times that in the other pipe
Step-by-step Solution
Detailed explanation
Diameter of first pipe, \(d_1=2 \mathrm{~cm}\) \(\therefore\) Radius, \(r_1=1 \mathrm{~cm}=10^{-2} \mathrm{~cm}\) Diameter of second pipe, \(d_2=4 \mathrm{~cm}\) \(\therefore \quad r_2=2 \mathrm{~cm}=2 \times 10^{-2} \mathrm{~m}\) If \(v_1\) and \(v_2\) are the velocities of…
