Question

The value of bulk modulus of a fluid is required to determine the-

• A. Euler number
• B. Mach number
• C. Froude number
• D. Reynolds number

Answer 1

Answer:

B. Mach number

Bulk modulus of a fluid is required to determine the Mach number, which is the ratio of inertia force to elastic force. Bulk modulus is the ratio of hydrostatic stress to volumetric strain. Mathematically, Mach Number (M) = V/C,
