in the equation below, what is the appropriate unit for Weber Number (We) if the equation is to be homogeneous in units 

We = pv2 L/o

p = density 

v= velocity based on cross section (m/s)

o = surface tension (n/m)

L = length (m)

 

Expert Solution
Step 1 Weber Number is Unitless

Basic defination of Weber Number is

FiFS

Where if Fi is Inertia force &

Fs is surface tension force

Hence, it is ration of Two forces so its Unitless
