, 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.
