1.	The volume of a liquid (v) flowing per second through a cylindrical tube depends upon the pressure gradient (p/l) radius of the tube (r ) coefficient of viscosity (eta) of the liquid by dimensional method the correct formula is
Answer» <P>`V ALPHA (PR^(4))/(ETA l)` `V oo (P r)/(eta l^(4))` `V prop (Pl^(4))/(eta r)` none Answer :A
