An increase in pressure of a liquid from 7.5 MPa to 15 MPa results into 0.2 percent decrease in its volume. The coefficient of compressibility of the liquid in m²/N is
- A. 0.267 * 10^-9
- B. 2.67 * 10^-9
- C. 1 * 10^-9
- D. None
Answer: A. 0.267 * 10^-9
Explanation: Beta = (dV/V) / dP = 0.002 / (7.5 * 10^6) = 0.267 * 10^-9.
