Question : 23

Total: 40

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}

^{-2}

)

0.262 m
0.664 m
0.819 m
0.455 m

Solution:

pressure = p, depth/height = h, density = d, gravity = g

p = hdg

$\frac{p}{dg} = h$

$\frac{9100}{10 \cdot 2000} = h$

0.455m
