Answers) /Already Graded A+
Cohesive Soil
Ans: Silt and clay.
Cohesionless Soil
Ans: Gravel, sand, stone.
Well
Ans: Deep groundwater deposits where underground water are available for
water supply and irrigation.
Water table
Ans: The level below the Earth's surface where the soil and gravel are
completely saturated with water.
Aquifers
Ans: Underground layers of rock or sand that hold water.
Phreatic table
Ans: The upper surface of the zone of saturation.
Laminar
Ans: Fluid flow where particles move parallel to adjacent layers without
crossing paths.
Turbulent
Ans: Flow characterized by irregular particle movement exchanging
momentum.

Bernoulli Principle
Ans: States that increase in kinetic energy per unit weight equals decrease in
potential energy per unit weight.
Torricelli Law
Ans: Theoretical velocity of a liquid jet from an orifice equals free-falling body
velocity.
Hydraulic grade line
Ans: The total energy line in fluid flow.
Critical flow
Ans: Open channel flow where Froude Number equals 1.
Open channel flow
Ans: Flow with a free surface subjected to atmospheric pressure.
Weir
Ans: Overflow structure across an open channel for flow measurement or
control.
Hydrometer Analysis
Ans: Test for determining grain size distribution of soils passing No. 200
sieve.
Hazen's Effective Size
Ans: Grain size corresponding to 10 percent passing on a distribution curve.
