A reservoir is filled with liquid of density 2000 kgm\(^{-1}\). Calculate the depth at which the pressure in the liquid will be equal to 9100 Nm\(^{-2}\) (g = 10 ms\(^{-2}\))
- A. 0.262 m
- B. 0.664 m
- C. 0.819 m
- D. 0.455 m
Correct Answer: D. 0.455 m
Explanation
pressure = p, depth = d, height = h, gravity = g
p = hdg
\(\frac{p}{hg} = d\)
\(\frac{9100}{10 * 2000} = d\)
0.455m
