Q4 of 24 Page 72

An ideal fluid flows through a pipe of circular cross-section made of two sections with diameters 2.5 cm and 3.75 cm. The ratio of the velocities in the two pipes is

Given:


Diameter of section1 = d1 = 2.5 cm


Diameter of section2 = d2 = 3.75 cm


According to the law of continuity,
