,hydraulic jump - 🧠ANSWER ✔✔A type of shock where the flow undergoes

a sudden transition from swift flow to tranquil flow


viscosity - 🧠ANSWER ✔✔A fluid property that measures the fluid's

resistance to shear stress


1/2 - 🧠ANSWER ✔✔The vena contracta of a circular orifice is

approximately ___ diameter downstream from the inner face of the orifice

plate:


neutral equilibrium - 🧠ANSWER ✔✔When the ship's metacenter and center

of gravity coincide at same point then the vessel is said to be in:


surface tension - 🧠ANSWER ✔✔A force within the surface layer of a liquid

that causes the layer to behave as an elastic sheet

, turbulent - 🧠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 - 🧠ANSWER ✔✔Type of flow where the flow rate does not

change over time.


uniform flow - 🧠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 - 🧠ANSWER ✔✔Uninterrupted flow in a fluid near a solid

boundary in which the direction of flow at every point remains constant:


continuous flow - 🧠ANSWER ✔✔Type of flow where at any time, the

discharge or flow rate at every section of the stream is the same.


critical flow - 🧠ANSWER ✔✔Type of flow in which, for a fixed rate of flow,

the specific energy is minimum.


incompressible flow - 🧠ANSWER ✔✔Type of flow in which the density of

the fluid is constant from one point to another.


rotational flow - 🧠ANSWER ✔✔Type of flow in which the fluid particles

rotate about their own axis while flowing along the streamlines.
