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 option: d
Let:
pressure = p
depth/height = h
density = d
gravity = g
p = hdg
\(\frac{p}{dg} = h\)
\(\frac{9100}{10 * 2000} = h\)
h = 0.455m
