Question
A U-tube is partially filled with water. Oil which does not mix with water is next poured into one side, until water rises by 25 cm on the other side. If the density of the oil is 0.8 g/cc, the oil level will stand higher than the water level by : -
Options
A.6.25 cm
B.12.50 cm
C.18.75 cm
D.25.00 cm
Solution
Pressure at point A = Pressure at point B
⇒ hρoll g = 25 cm ρwaterg
⇒ h =
= 31. 25 cm
⇒ height difference
= 31.25 - 25 = 6.25 cm
⇒ hρoll g = 25 cm ρwaterg
⇒ h =
= 31. 25 cm⇒ height difference
= 31.25 - 25 = 6.25 cm
