What is the pressure required to reduce the given volume of water by 1 % ? (Bulk modulus K = 2 × 10 8 N m - 2 )

Options

  1. A2 × 10 5   N   m - 2
  2. B2 × 10 6   N   m - 2
  3. C2 × 10 7   N   m - 2
  4. D2 × 10 8   N   m - 2

Correct answer

B. 2 × 10 6   N   m - 2

Step-by-step solution

Given that Bulk modulus K = 2 × 10 8   N   m - 2 Volume change ∆ v v = 1 % Bulk modulus is given by k = p ∆ v v ⇒ p = k ∆ v v ⇒ p = 2 × 10 8 0 . 01 = 2 × 10 6
