A dimensionally consistent relation for the volume V of a liquid of coefficient of viscosity

\eta

flowing per second through a tube of radius r and length l and having pressure p across its end, is

View answer and explanation

Correct option: A

V = \frac{{\pi p{r^4}}}{{8\eta l}}

Option A (

V = \frac{{\pi p{r^4}}}{{8\eta l}}

) is correct because it is the only option that is dimensionally consistent with the volume flow rate.

Statement-I: Random errors can be positive or negative.
Statement-II: Cause of random errors are uncertain. An object is moving through the liquid. The viscous damping force acting on it is proportional to the velocity. Then dimension of constant of proportionality is The error due to parallax is a: 2.34 is obtained by rounding of the number The dimensional formula of self-inductance is The dimension of
