Question

Obtain an expression for volume of the liquid passing through a capillary tube per second by using dimension

Answer 1

Volume per sec = L^3 T^-1

Now according to above equation

V= P r^4 / ( neta ) l

=( M L^-1 T^-2 ) ( L^4 )

-------------------------------

( M L^-1 T^-1 ) ( L )

= L^3 T^-1

Hence proved !!!
