71) State the following statement correct or wrong.
Statement: The weight of water is equal to the total voids’ weight in a 3-phase soil system.
- a) True
- b) False
Answer: a) True
The weight of total voids is the combination of weights of water & weight of air.
• Wv = The weight of total voids.
• Ww = The weights of water.
• Wa = The weight of air.
∴ Wv = Ww + Wa
Actually, the air’s weight is considered to be negligible.
Wv =Ww + Wa
Wv =Ww + 0
Hence, the conclusion is the total void’s weight is equal to the weight of water.
