A reservoir of capacity 0.01 m³ is completely filled with a fluid of compressibility 0.75 * 10^-9 m²/N. The amount of fluid that will spill over if pressure is reduced by 2 * 10^7 N/m² is

  • A. 1 * 10^-4
  • B. 1.5 * 10^-4
  • C. 0.15 * 10^-4
  • D. None

Answer: B. 1.5 * 10^-4

Explanation: dV = V * Beta * dP = 0.01 * 0.75e-9 * 2e7 = 1.5e-4 m³.
