A glass tube has several different cross-sectional areas with the values indicated in the figure . A piston at the left end of the tube exerts pressure so that mercury within the tube flows from the right end with a speed of `8.0` m/s . Three points with in the tube are labeled A , B and C . (Atmospheric pressure is `1.01 xx 10^(5) N//m^(2)` , Density of mercury is `13600 kg //m^(3)`) .

What is the total pressure at point A ?

A

`1.01 xx 10^(5) Pa`

B

`4.27 xx 10^(5) Pa`

C

`2.02 xx 10^(5) ` Pa

D

`3.26 xx 10^(5)` Pa
