What would be the major difference between aerodynamic and hydrodynami

1.	What would be the major difference between aerodynamic and hydrodynamic analyses?(a) Temperature(b) Reynolds Number(c) Velocity(d) DomainThis question was posed to me during an interview for a job.My question comes from Applications in chapter Philosophy of Computational Fluid Dynamics of Computational Fluid Dynamics
Answer» Correct CHOICE is (b) Reynolds Number The explanation is: Reynolds number of the flow would be the major CHANGE as the density and viscosity of water will be higher than that of air. Therefore, while modelling a hydrodynamic flow, CARE should be taken.
