Water is flowing steadily through a horizontal tube a of non uniform cross-section. If the pressure of water is `4xx10^(4)N//m^(2)` at a point where cross-section is `0.02m^(2)` and velocity of flow is `2m//s`, what is pressure at a point where cross-section reduces to `0.01m^(2)`

Options

A. `1.4xx10^(4)N//m^(2)`
B. `3.4xx10^(4)N//m^(2)`
C. `2.4xx10^(-4)N//m^(2)`
D. None of these

Answer

C
