WebMar 5, 2024 · √Cau = U √E ρ In the liquid phase the speed of sound is approximated as c = E ρ Using equation (61) transforms equation (60) into √Cau = U c = M Thus the square root of Ca is equal to Mach number in the liquid phase. In the solid phase equation (62) is less accurate and speed of sound depends on the direction of the grains. WebCategory for dimensionless numbers in the area of fluid mechanics.
