Explanation / Answer

by equation of continuity

velocity at a * area at a=velocity at b*area at b

Now dia of B is greater, hence area at b>area at a

Hence velocity at a> velocity at b

Now pressure generally varies with square of velocity

Hence Pa>Pb

Pressure at a is greater than pressure at b
