The cylindrical tube of a spray pump has a crosssection of

8.0 \mathrm{~cm}^2

, one end of which has 40 fine holes each of diameter

1.0 \mathrm{~mm}

. If the liquid flow inside the tube is

1.5 \mathrm{~m} \mathrm{~min}^{-1}

, what is the speed of ejection of the liquid through the holes?

View answer and explanation

Correct option: A

0.637 \mathrm{~ms}^{-1}

Option A (0.637 m/s) is correct because it accurately calculates the speed of ejection of the liquid using the equation of continuity.

poise. A liquid rises to a height of 2 cm in a capillary tube. The angle of contact between the solid and the liquid is zero. The tube is depressed more so that the top of capillary tube is only one cm above the liquid. Then the apparent angle of contact between the solid and liquid is An object weights
