Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the formula for calculating theoretical specific gravity?
- A: G_t = (W1 + W2 + W3 + Wb) / (W1/G1 + W2/G2 + W3/G3 + Wb/Gb)
- B: G_m = W_m / (W_m – W_w)
- C: V_v = (G_t - G_m) / G_t * 100
💡 Hint: Look for the formula that accounts for weights and specific gravities.
Question 2
True or False: The bulk specific gravity value is affected by air voids.
- True
- False
💡 Hint: Consider how density is impacted by gaps.
