Q1: Weber number is the ratio of inertia force toA
surface tension
B
gravitational force
C
elasticity
D
viscosity.
ANS:A - surface tension Weber number (We) is the ratio of inertia force to surface tension force. It is defined as: We = Inertia forceSurface / tension force Inertia force typically refers to the force associated with the momentum of a fluid, while surface tension force is the force due to the cohesive nature of molecules at the surface of a liquid. |
