Question

The soil hydraulic head is expressed by
(A). Potential energy per unit mass of soil water.
(B). Potential energy per unit volume of soil water.
(C). Potential energy per unit weight of soil water.
(D). Height of standing water on the soil surface.
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only
• B. (A), (C) and (D) only
• C. (A), (B), (C) and (D)
• D. (C) only

Hint:

Remember: - Energy per unit weight = Length dimensions (meters/centimeters head) - Energy per unit volume = Pressure dimensions (Pascalbar) - Energy per unit mass = Chemical potential ($\text{J/kg}$)

Answer 1

The Correct Option is D
