: Variables Related to Leaf
The
effect of leaf surface was studied by measuring the distance traveled
by a single water droplet put on the leaf surface. The graph below
shows that a drop travels a greater distance in case of surfaces
(leaves as well as controls) with greater number of hairs, ridges and
bumps. Between the three surfaces, hairy leaves have the greatest
run-off.
The
growing angle of leaves ranges from 30-60 degrees. A ramp with
adjustable angle was used to conduct experiments on surfaces (leaves
and control) at 30 and 60 degrees. As the angle is doubled, the
distance traveled by the drop doubles.
Talc
powder was used to simulate dust. A layer of Talc on the surface
reduces runoff by almost 50%.
