Consider, π and π are unit vectors along x and y directions of a Cartesian (π₯, π¦) coordinate system, respectively and π‘ is time. Temperature (π) and fluid velocity (πβ ) are given for a flow field as: π= π₯2 + π¦π‘+ 35 πβ = (4π₯π¦)π+ (π₯π‘β2π¦2)π The total rate of change of temperature in the flow field (in integer) for time π‘= 2 at a point (2, 3) is ________
