Test: Compressibility & Bulk Modulus - Question 1
Save

Which one of the following is the correct relation between compressibility β and Bulk Modulus k

Detailed Solution: Question 1

Explanation: Compressibility β of a liquid is deβned as the ratio of volumetric strain to the compressive stress while Bulk Modulus is the ratio of compressive stress to volumetric strain. Hence, β = 1/k is the correct relation.

Test: Compressibility & Bulk Modulus - Question 2
Save

Which one of the following is true about Bulk Modulus of elasticity?

Detailed Solution: Question 2

Explanation: Bulk Modulus k is related to the compression of a liquid and the decrease in volume per unit volume. It is the ratio of compressive stress to the volumetric strain.

Test: Compressibility & Bulk Modulus - Question 3
Save

The value of the Bulk Modulus of elasticity for an incompressible fluid is

Detailed Solution: Question 3

Explanation: k = 1/β, where k= Bulk Modulus of elasticity and β= compressibility. For an incompressible fluid, β=0, thus the value of k will tend to infinity.

Test: Compressibility & Bulk Modulus - Question 4
Save

Three fluids 1, 2 and 3 have Bulk Moduli of k1, k2 and k3 respectively. If k1 > k2 > k3, which liquid will have the highest compressibility?

Detailed Solution: Question 4

Explanation: k = 1=β, where k= Bulk Modulus of elasticity and β= compressibility. If k1 > k2 > k3, then β1 < β2 < β3. Thus, liquid 3 will have the highest compressibility.

Test: Compressibility & Bulk Modulus - Question 5
Save

Broadly speaking water is :

Detailed Solution: Question 5

Explanation:Stainless Steel with Bulk Modulus 163*109 Pa is aprox. 80 times harder to compress than water with Bulk Modulus 2.15*109 Pa.
