If the pressure head of water is 100 m and the specific gravity of kerosene is 0.81, what is the pressure head of kerosene?

[A] 123.5 m of kerosene
[B] 241.3 m of kerosene
[C] 75.1 m of kerosene
[D] 52.4 m of kerosene

ANSWER= [A] 123.5 m of kerosene

Detailed Solution for Civil Engineering Exam

For equal pressure,

100 γ_w = h γ_kerosene

h = (100 γ_w)/γ_kerosene = (100/0.81)

h = 123.46 m

h = pressure head of kerosene
