Consider a unidirectional fluid flow with the velocity field given by
$$
V(x, y, z, t)=u(x, t) \hat{\imath}
$$
where $u(0, t)=1$. If the spatially homogeneous density field varies with time $t$ as
$$
\rho(t)=1+0.2 e^{-t}
$$
the value of $u(2,1)$ is ______________. (Rounded off to two decimal places)
Assume all quantities to be dimensionless.
