EV350 Environmental Engineering WPR1 Exam
Questions and Verified Answers – Complete Study Notes
and Practice Definitions
Introduction:
This document contains verified exam questions and answers for
EV350 Environmental Engineering WPR1. It covers important
environmental engineering concepts including aquifers, hydrology,
mass balance, dissolved oxygen, BOD, COD, infiltration, hydraulic
conductivity, and first-order kinetics.
The material is organized in a concise question-and-answer format,
making it useful for revision, memorization, and exam preparation.
It also includes groundwater flow terminology and water quality
parameters commonly tested in environmental engineering courses.
Exam Questions and Answers
Confined Aquifer --- correct precise answer ---an aquifer that is
confined by an impermeable layer of rock
Unconfined Aquifer --- correct precise answer ---an aquifer that
has water that seeps from the ground surface directly aboce the
aquifer.
Cone of Depression --- correct precise answer ---occurs in an
aquifer when groundwater is pumped from a well. Depression of
water levels around well
,Mole/Liter (or M) --- correct precise answer ---molecular
concentration (M)
ppm --- correct precise answer ---parts per million
pH --- correct precise answer ---14-0 scale. How acidic or basic
Solubility Constant (Ksp) --- correct precise answer ---the product
of the concentration of the ions that are present in a saturated
solution
Precipitation --- correct precise answer ---the process of
precipitating a substance from a solution
Acid/Bass reaction --- correct precise answer ---When an acid and a
base are placed together, they react to neutralize the acid and base
properties, producing a salt.
Biochemical Oxygen Demand (BOD) --- correct precise answer ---is
the amount of dissolved oxygen needed (i. e., demanded) by aerobic
biological organisms to break down organic material present in a
given water sample at certain temperature over a specific time
period.
, Environmental Engineering --- correct precise answer ---Protection
of human populations, protection of environments, improvement of
environmental equality
Sustainability --- correct precise answer ---Capacity to endure, how
biological systems remain diverse
Mass Balance --- correct precise answer ---Application of the
conservation of mass
Steady State --- correct precise answer ---Universe is eternal and
maintained as a net zero
Completely Mixed --- correct precise answer ---Completely mixed
solution
Influent --- correct precise answer ---Flowing in
Effluent --- correct precise answer ---Flowing out
Decay Constant --- correct precise answer ---k
