The barometric reading at a place is 73.5m Hg. Calculate the pressure at a point 30m below the surface of water contained in a reservoir at the place. [g = ms-2, density = 1.2 x 104kg m-3, density of water = 1.0 x 103m-3]
- A. 4.0 x 105 Nm-2
- B. 3.0 x 105 Nm-2
- C. 2.0 x 105 Nm-2
- D. 1.0 x 105 Nm-2
Correct Answer: B. 3.0 x 105 Nm-2
