360920 In the water coming out of the mouth of a tap and falling vertically in streamline flow forms a tapering column. i.e., the area of cross-section of the liquid column decreases as it moves down at the mouth of the tap the area of cross-section is \(2.5\;c{m^2}\) and the speed of water is \(3\;m{\rm{/}}s\). The area of cross-section of the water column \(80\;cm\) below the tap is:
