Question

# Let C1 be the velocity of pressure wave travelling along rigid pipe carrying water with its bulk modulus 2.16×109 N/m2. Let C2 be the velocity of pressure wave travelling along a rigid pipe carrying oil of relative density 0.600 with its bulk modulus as 1.296×109 N/m2 through a similar pipe. What will be the ratio C1C2?

Solution

## The correct option is C 1.0Velocity of pressure wave is given by C=√Kρ C1=√2.16×1091000 Now, C2=√1.296×1090.6×1000 ∴ C1C2=1
