Question

A current density for a fluid flow is given by,
$\overrightarrow{j} (x,y,z,t) = \frac{8e^t}{ (1+x^2+y^2+z^2)} \hat{x}$
At time t = 0, the mass density p(x, y, z, 0) = 1.
Using the equation of continuity, $p(1,1,1,1)$ is found to be ___________ (Round off to 2 decimal places).

Answer 1

The correct answer is :2.70 to 2.74 (approx)
