above center of gravity - correct answer Where is the metacenter for stable
equilibrium?
unstable equilibrium - correct answer When the metacenter of a floating body is
lower than the center of gravity, then the body will be in?
center of gravity of the floating body and the metacenter - correct answer The
metacentric height is the distance between the
specific weight - correct answer The weight per unit volume of a liquid at a standard
temperature and pressure is called
water hammer - correct answer A pressure surge or wave caused when a fluid in
motion is forced to stop or change direction suddenly (momentum change) is referred to in hydraulics
as:
hydraulic jump - correct answer A type of shock where the flow undergoes a sudden
transition from swift flow to tranquil flow
viscosity - correct answer A fluid property that measures the fluid's resistance to
shear stress
1/2 - correct answer The vena contracta of a circular orifice is approximately ___
diameter downstream from the inner face of the orifice plate:
neutral equilibrium - correct answer When the ship's metacenter and center of
gravity coincide at same point then the vessel is said to be in:
,surface tension - correct answer A force within the surface layer of a liquid that
causes the layer to behave as an elastic sheet
velocity head - correct answer Minor losses through valves, fittings, bends,
contractions etc. are commonly modeled as proportional to
b - correct answer The best hydraulic cross section for a trapezoidal channel of base
width b is one for which the length of the side edge of the flow section is:
turbulent - correct answer When the path lines of the individual particles of a
flowing liquid are irregular curves and continually cross each other and form a complicated network, the
flow is called:
steady flow - correct answer Type of flow where the flow rate does not change over
time.
uniform flow - correct answer Type of flow where the mean velocity of flow for a
given length or reach is the same at every cross section
laminar flow - correct answer Uninterrupted flow in a fluid near a solid boundary in
which the direction of flow at every point remains constant:
continuous flow - correct answer Type of flow where at any time, the discharge or
flow rate at every section of the stream is the same.
critical flow - correct answer Type of flow in which, for a fixed rate of flow, the
specific energy is minimum.
incompressible flow - correct answer Type of flow in which the density of the fluid is
constant from one point to another.
rotational flow - correct answer Type of flow in which the fluid particles rotate
about their own axis while flowing along the streamlines.

angle between the two planes is
Air - correct answer Compression of soil occurs rapidly if voids are filled with
Sand - correct answer Cohesionless soil is

drainage is allowed during the first stage only and not during the second stage, the test is known as
