Question
The approximate depth of an ocean is 2700 m.The compressibility of water is 45.4 x 10-11 Pa-1 and density of water is 103 kg/m3. What obtained at the bottom of the ocean?
-
0.8 x10-2
-
1.0 x 10-2
-
1.2 x 10-2
-
1.4 x 10-2
Solution
C.
1.2 x 10-2
Given d = 2700m
Compressibility =454 x 10-11 per pascal
The pressure at the bottom of ocean is given by
= 103 x 10 x 2700 = 27 x 106 Pa
So,fractional compression =compressibilty x pressure
= 45.4 x 10-11 x 27 x 106 = 1.2 x 10-2
