Atmospheric pressure varies with
The atmospheric pressure varies with altitude as the density of air decreases as we rise up and the air becomes rarer. For example Pressure at sea level is taken as 76 cm of Mercury Column, which is one atmosphere. For every 105m rise in height, pressure decreases by 1 cm of mercury column.

See lessWhich one of the following equation is applicable to unsteady flow in open channels :
By virtue of its free surface, unsteady channel flow is essentially non-uniform flow and it can therefore be conveniently considered in two categories, gradually varied and rapidly varied unsteady flow. Such a classification is made on the same basis as that used for steady non-uniform flow.

See lessAn error of 1% in measuring the head of water over the crest of a triangular notch, produces an error in the discharge which is equal to
Therefore, an error of 1% in measuring H will produce an error of 0.00436% in discharge over a triangular notch. Conclusion: Hence, the correct option is D) 2.5% which is the closest option to the calculated error in discharge over a triangular notch.
