VERIFIED SOLUTIONS
◉ Cohesionless Soil. Answer: gravel, sand, stone
◉ Aquifers. Answer: Deep groundwater deposits where underground
water are available for water supply and irrigation is known as:
◉ Laminar. Answer: In a fluid flow, if the fluid travels parallel to the
adjacent layers and the paths of individual particles do not cross, the
flow is said to be.
◉ Turbulent. Answer: A condition of flow characterized when fluid
particles move in very irregular paths, causing an exchange of
momentum for portion of the liquid to another is.
◉ Bernoulli Principle. Answer: A principle of flow measurement which
states that the increase in kinetic energy per unit weight is equal to the
decrease in the potential energy per unit weight, is known as:
,◉ Torricelli Law. Answer: "The theoretical velocity of a jet of liquid
issuing out of an orifice under a head of h being equal to the velocity of
a free-falling body dropping through a height of h" is known as:
◉ Velocity Head. Answer: The difference between the hydraulic grade
line and energy grade line is.
◉ Critical flow. Answer: A type of open channel flow where the Froude
Number is equal to 1.
◉ Open channel flow. Answer: It is defined as a conduit in which the
liquid flows with a free surface subjected to atmospheric pressure. The
flow is caused by the slope of the conduit and the liquid surface:
◉ Weir. Answer: It is an overflow structure built across an open channel
for the purpose of measuring or controlling the flow.
◉ Hydrometer Analysis. Answer: Is the test used to determine the grain
size distribution of the soils passing the No. 200 sieve.
◉ Hazen's Effective Size. Answer: It is the grain size corresponding to
10 percent passing on a grain-size distribution curve.
◉ Relative density. Answer: Is the ratio of the difference between the
void ratios of a cohesionless soil in its loosest state and existing natural
,state to the difference between its void ratio in the loosest and densest
states
◉ Soil Consistency. Answer: Provides a means of describing the degree
and kind of cohesion and adhesion between the soil particles as related
to the resistance of the soil to deform or rupture.
◉ It is a field measure of the ability of the soil to withstand applied
stress or pressure as applied using the thumb and forefinger.. Answer:
Rupture Resistance
◉ Cohesion. Answer: Is the attraction of one water molecule to another
resulting from hydrogen bonding (water-water bond).
◉ Adhesion. Answer: It involves the attraction of a water molecule to a
non-water molecule (water-solid bond).
◉ Stickiness. Answer: The capacity of soil to adhere to other objects. It
is estimated at moisture content that displays maximum adherence
between thumb and forefinger.
◉ Plasticity. Answer: Degree a soil can be molded or reworked causing
permanent deformation without rupturing.
, ◉ Liquid limit. Answer: Is defined as the moisture content at which soil
begins to behave as a liquid material and begins to flow.
◉ Plastic limit. Answer: Is defined as the moisture content at which soil
begins to behave as a plastic material: It is also defined as the moisture
content at which the soil crumbles when rolled into a thread of 3.18 mm
in diameter.
◉ Shrinkage Limit. Answer: Is defined as the moisture content at which
no further volume change occurs with further reduction in moisture
content.
◉ Compaction. Answer: Is the densification of soil by removal of air,
which requires mechanical energy.
◉ Optimum Moisture Content. Answer: The moisture content at which
the maximum dry unit weight of soil is attained
◉ Vibroflotation. Answer: It is a technique for in situ densification of
thick layers of loose granular soil deposits.
◉ Flow line. Answer: A line along which water particle will travel from
upstream to the downstream side in the permeable soil medium.
