- Reynolds number is significant in
- Mach number is significant in
- A piece of metal of specific gravity 13.6 is placed in mercury of specific gravity 13.6, what fraction of it volume is under mercury?
- The viscosity of a gas
- The pressure at the summit of a syphon is
- In a free vortex motion, the radial component of velocity everywhere is
- A fluid in equilibrium can’t sustain
- The value of the coefficient of compressibility for water at ordinary pressure and temperature in kg/cm is equal to
- If velocity is zero over l/3rd of a cross-section and is uniform over remaining 2/3rd of the cross-section, then the correction factor for kinetic energy is
- With the same cross-sectional area and immersed in same turbulent flow, the largest total drag will be on
A.
supersonics, as with projectile and jet propulsion |
B.
full immersion or completely enclosed flow, as with pipes, aircraft wings, nozzles etc |
C.
simultaneous motion through two fluids where there is a surface of dis-continuity, gravity forces, and wave making effect, as with ship’s hulls |
D.
all of the above |
