A liquid flows downwards thorough a tapered vertical pipe, as shown in the given figure. The diameter at Section 1 is twice that at Section 2 and the pressures at Sections 1 and 2 are equal. Assume zero loss of energy between two sections. If the distance between Sections 1 and 2 is 1.5 m, the velocity of fluid passing at Section 2 is:
1
2.80 m/s
2
5.60 m/s
3
10.20 m/s
4
1.40 m/s
