Question

For Following Multiple Choice All Correct Answers Which Applied To Each Question.

1. The hydraulic head, h, is equal to the sum of the:

• pressure, elevation, and velocity heads.
• fluid pressure and the elevation head.
• pressure head and elevation head.
• hydraulic conductivity and intrinsic permeability.

2. Henry Darcy (1865) measured the flow of water through sand-filled columns, and found that the total discharge, Q, through the column was:

• proportional to the column cross-sectional area, A.
• inversely proportional to the length, L, of the column.
• proportional to the head difference across the column.
• proportional to the pressure difference across the column.

3. For flow through porous media, the specific discharge, q [L T-1], may be defined as:

• the total discharge divided by the column width.
• the total discharge divided by cross-sectional area.
• the total discharge divided by the porosity.
• the Darcy velocity.

4. What is (are) the difference(s) between hydraulic conductivity, K, and intrinsic permeability, k?

• The intrinsic permeability is a measure of the ability of a medium to transmit water only.
• They have different dimensions.
• The intrinsic permeability does not depend on fluid properties.
• The hydraulic conductivity does not depend on fluid properties.

Answer 1

Anwer Hydraullis Head pressure Head + elevation Head + velocity Head (op hon - 1) =KA x A (option-1) (3) specific discharges totel discharge cross sectionarea (option - 2) 14) intrinsic permeability does not depends on fluid properties option (3)
