- A piece of metal of specific gravity 7 floats in mercury of specific gravity 13.6. What fraction of its volume is under mercury?
- The power transmitted through a pipe is (where w = Specific weight in N/m3, and Q = Discharge in m3/s)
- In a single casing, multistage pump running at constant speed, the capacity rating is to be slightly lowered. It can be done by
- An air vessel is provided at the summit in a siphon to
- In a free vortex motion, the radial component of velocity everywhere is
- The celerity (velocity) of a pressure wave in a fluid is given by (where K = Bulk modulus, and ρ = Density of the fluid)
- When a cylindrical vessel containing liquid is revolved about its vertical axis at a constant angular velocity, the pressure
- A fluid in equilibrium can't sustain
A.
Supersonics, as with projectiles 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 discontinuity, gravity force, and wave making effects, as with ship's hulls |
D.
All of the above |
