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 by

A

`–1, –1, 1`

B

`–1, –1, –1`

C

`1, 1, 1`

D

`1, –1, –1`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_c = eta^(x) rho^(y) r^(z)`
Critical velocity is given by `V_c = (Reta)/(2rhor)`
so `x =1 " " y =-1 " " z=-1`
