To test for the capillary actio of water in different soil samples

(2b)
Spec E; it has lowest capillarity
Spec F; it has the highest capillarity
Spec G; the capillarity is moderate

A ranging pole is a robust, often brightly colored pole used primarily in surveying and construction to mark positions and sight lines. Typically, these poles are made from wood or metal, and they are painted in alternating bands of red and white or black and white to ensure high visibility over long distances. Ranging poles usually measure about 2 to 3 meters in length and may be equipped with a pointed end to easily stick them into the ground.

(1b)
(i)Spec A; ranging pole is primarily used to establish sight lines and mark positions on a site during surveying.
(ii)Spec B; An arrow in surveying is a small metal pin that is used to mark positions on the ground where measurements are taken.
(iii) Spec C; A measuring tape is a flexible ruler used to measure distance or size.
(iv)Spec D; A wooden peg is often used to permanently mark the boundaries of surveyed land.

(1c)

(1d)
(i) Regularly clean the poles after use to remove dirt and mud that can obscure the visibility of the markings.
(ii) Clean arrows of dirt and rust regularly to prevent deterioration.
(iii)After each use, clean the tape by pulling it through a clean rag to remove any dirt, mud, or debris that might have accumulated.
(iv)Before use, ensure that the wooden pegs are dry and free from cracks.
