A network of pipes conveying water to a city has the following specifications. The diameter of a main pipe is 30 cm and it branches into two pipes of diameters 20 cm and 15 cm respectively. If the average velocity in the main pipe is 2.5 m/s and the average velocity in the 20 cm pipe is measured as 2 m/s, what is the velocity in the 15 cm pipe?




ANSWER= [D] 6.44 m/s

Detailed Explanation

From the continuity equation

D12/4)V1 = D22/4)VD32/4)V3

D12V1 = D22VD32V3

V= (D12V1 – D22V2)/D32 = (D1/D3)2 V1 – (D2/D3)2 V2

V= (30/15)2 × 2.5 – (20/15)2 × 2

V3 = 4 × 2.5 – (4/2.25) × 2 = 6.44 m/s

V3 = 6.44 m/s
