For an inviscid fluid with density } 1 \mathrm{~kg} / \mathrm{m}^{3}, \text { the Cartesian velocity field is given as:
$\mathbf{u}=(-2 x+y) t \mathbf{i}+(2 x+y) t \mathbf{j} \mathrm{m} / \mathrm{s}$
Neglecting the body forces, find the magnitude of pressure gradient in $(\mathrm{Pa} / \mathrm{m})$ at
$(x, y)=(1 \mathrm{~m}, 1 \mathrm{~m}) \text { at } t=1 \mathrm{~s}.$
$\text {(Round off to two decimal places) }$
