In dimension of circal velocity `v_(0)` liquid following through a take are expressed as `(eta^(x) rho^(y) r^(z))` where `eta, rhoand r `are the coefficient of viscosity of liquid density of liquid and radius of the tube respectively then the value of `x,y` and `z` are given byA. `1, 1, 1`B. `1, -1, -1`C. `-1, -1, 1`D. `-1, -1, -1` |

Answer» Correct Answer - B `v_c prop [ eta ^(x) rho ^(y) r^(z)]` `[L^(1)T^(-1)] prop [M^(1)L^(-1) T^(-1)]^(x) [M^(1)L^(-3) ] ^(y) [L^(1)]^(z)` `[L^(1)T^(-1)] prop [ M^(x+y)] [ L^(-x + 3y+ z)] [ T^(-x)]` taking comparision on both size ` x+y =0, -x - 3y +z =1, -x =-1` `rArr x =1, y =-1, z=-1` |
