For a compressible flow, Mach Number (M) is given by which of the following expression?
एक संपीड़ित प्रवाह के लिए, मैक संख्या (M) निम्नलिखित में से किस अभिव्यक्ति द्वारा दी गई है?
Where
V = velocity of fluid in compressible flow
C = speed of sound in air
The Mach number (M) is simply the ratio of the velocity (v) divided by the speed of sound at that altitude (c). Mach number is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound.
Here,
v= Velocity of fluid in compressible flow
c = speed of sound in air
Hence, the
correct option is (C).
