- In an incompressible flow of fluid, the fluid
- The drag co-efficient for a bacterium moving in water at 1 mm/s, will be of the following order of magnitude (assume size of the bacterium to be 1 micron and kinematic viscosity of water to be 10⁻⁶m²/s).
- The ratio of hydrodynamic boundary layer to thermal boundary layer thickness in case of liquid metals is
- The hydraulic radius for flow in a rectangular duct of cross-sectional dimension H, W is
- For water, when the pressure increases, the viscosity
- Boundary layer thickness in laminar flow over a flat plate increases as(where, d = distance from the leading edge.)
- Boundary layer thickness in turbulent flow over a flat plate increases as(where, d = distance from the leading edge.)
- Steady flow occurs, when the
