Questions & Answers

Q: What are the different types of forces acting on fluid in fluid dynamics?

In fluid dynamics, forces include pressure, gravity, compressibility, viscosity, and turbulence, each contributing to the fluid motion based on conditions like flow direction and viscosity gradients.

Q: Why is the force due to turbulence significant in fluid dynamics?

Turbulence generates additional resistance to fluid flow by causing adjacent fluid layers to interact, resulting in wave formation and complicating fluid motion dynamics.

Q: How does the absence of force due to turbulence impact fluid motion equations?

If the force due to turbulence is zero, equations like Reynolds equation or Navier-Stokes equation simplify to consider only pressure, gravity, and viscosity forces, defining laminar flow characteristics.

Q: What defines an ideal fluid in fluid dynamics?

An ideal fluid has zero viscosity, making it flow without internal resistance, simplifying equations to consider only pressure and gravity forces in defining fluid motion.
