Question

There are four variables, namely, E (volume modulus of elasticity), p (pressure per unit area). g(acceleration due to gravity) and $\mu$ (viscosity of water). They are associated with Mach, Euler, Froude and Renylods number, respectively, in the order

• A. E, p,$\mu$, g
• B. p, E, $\mu$, g
• C. p, E, g, $\mu$
• D. E, p, g, $\mu$

Answer 1

The correct option is D E, p, g, $\mu$

$Machnumber=\frac{V}{\sqrt{E/\rho }}$

$Eulernumber=\frac{\Delta p}{\frac{1}{2}\rho V^2}$

$Froudenumber=\frac{V}{\sqrt{gy}}$

$Reynoldsnumber=\frac{\rho VL}{\mu }$
