The specific gravity of a soil is 2.60. Assuming the soil is perfectly dry, what is the dry unit weight if the void ratio is 0.78?
- 15.5 kN/m³
- 14.5 kN/m³
- 16.5 kN/m³
- 17.5 kN/m³
Show answer & explanation
Answer: B. 14.5 kN/m³
Dry unit weight (γd) = (Gs * γw) / (1 + e) = (2.60 * 9.81) / (1 + 0.78) = 14.45 kN/m³ ≈ 14.5 kN/m³

What is the most commonly used coagulant for water treatment?
- Sodium Chloride
- Calcium Carbonate
- Alum
- Potassium Permanganate
Show answer & explanation
Answer: C. Alum
Alum (Aluminum Sulfate) is the most widely used coagulant due to its effectiveness in removing turbidity and color from water.

A simply supported beam of span L carries a uniformly distributed load of w per unit length over the entire span. What is the maximum bending moment?
- wL/2
- wL²/4
- wL²/8
- wL²/12
Show answer & explanation
Answer: C. wL²/8
For a simply supported beam with UDL, the maximum bending moment occurs at the center and is given by wL²/8.

A wastewater sample has a BOD5 of 200 mg/L and a BOD rate constant (k) of 0.23 per day (base e). What is the ultimate BOD?
- 200 mg/L
- 435 mg/L
- 870 mg/L
- Cannot be determined
Show answer & explanation
Answer: B. 435 mg/L
Ultimate BOD (L0) = BOD5 / (1 - e^(-kt)) = 200 / (1 - e^(-0.23 * 5)) = 434.87 mg/L ≈ 435 mg/L

The hydraulic radius of a circular sewer of diameter D flowing half-full is:
- D/2
- D/4
- D/8
- D
Show answer & explanation
Answer: B. D/4
Hydraulic radius (R) = Area/Wetted Perimeter. For a half-full circular sewer, Area = πD²/8 and Wetted Perimeter = πD/2. Therefore, R = (πD²/8) / (πD/2) = D/4

What is the primary function of a transition curve in highway design?
- To improve drainage
- To increase the superelevation rate linearly
- To reduce the overall length of the highway
- To provide a smooth transition between a straight section and a circular curve
Show answer & explanation
Answer: D. To provide a smooth transition between a straight section and a circular curve
The main purpose of a transition curve is to gradually introduce superelevation and change the radius between a straight section and a circular curve for a comfortable driving experience.

Which of the following methods is most accurate for determining the average depth of rainfall over an area?
- Arithmetic Mean Method
- Thiessen Polygon Method
- Isohyetal Method
- Graphical Method
Show answer & explanation
Answer: C. Isohyetal Method
The Isohyetal method is considered the most accurate because it considers the actual rainfall distribution pattern by drawing lines of equal rainfall depth (isohyets).
