A reservoir 500 m deep is filled with a fluid of density 850 kgm-3. If the atmospheric pressure is 1.05 x 105 Nm-2, the pressure at the bottom of the reservoir is.
[g = 10ms-2]
[g = 10ms-2]
-
A.
4.72 x 106 Nm-2 -
B.
4.36 x 106 Nm-2 -
C.
4.28 x 106 Nm-2 -
D.
4.25 x 106 Nm-2
Correct Answer: Option D
Explanation
In general, pressure varies with depth in the relation p = lgh
= 850 x 10 x 500
= 4250000
= 4.25 x 106 NM-2
