Answer:
Explanation:
Given that;
diameter (d) = 10cm/2 = 0.1m/2 = 0.05 m
length (l) = 10 cm = 0.1 m
porosity = 50%
height (h) = 30 cm = 0.3 m
time (t) = 5 s
volume (v) = 60 cm³ = 60 × 10⁻⁶ m³
Q (flow rate) =
Q =
Q =
From constant head method, we use the relation K = to determine the hydraulic conductivity ; we have:

Answer:
The cohesive forces of mercury are much stronger than its adhesive forces.
Explanation:
Cohesive forces are forces that exist between the particles that compose a substance while adhesive forces refer to forces that exist between the particles of a substance and those of another substance.
The cohesive forces in mercury far outweigh the adhesive forces between the mercury drops and glass. Hence when mercury is put into a capillary tube, its meniscus is convex because cohesive forces tend to draw the liquid mercury into a drop.
Hence, the surface tension in mercury makes the mercury in the capillary tube to fall below the height of the mercury in the dish.
