The cylindrical tube of a spray pump has a cross-section of `8 cm^2`, one end of which has `40` fine holes each of area `10^-8 m^2`. If the liquid flows inside the tube with a speed of `0.15 m min^-1`, the speed with which the liquid is ejected through the holes is.

A

50 m`s^(-1)` ¹

B

5 m`s^(-1)`

C

0.05 m`s^(-1)`

D

0.5 m`s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Since, `A v` =constant
`implies a_2 v_2 = a_1 v_1`
`implies 40xx10^(-8) xx v=(8xx10^(-4)xx0.15)/(60) implies v =5 m// s`.
