What is the average tape?
Students and specialists in forestry, tree physiology and forest ecology must often measure trees growth. They usually use a dendrometer or a special measuring belt. The tape is also known as D-Tape, the type of dendrometer used to measure the tree diameter.
Tape measurement diameters are usually made of fabric or metal and calibrated in units 3.14 or from an estimate of a unit, inches or centimeters. They are generally used to measure the diameter of the tree at the breast height. This is considered four and a half feet (137,16 centimeters) above the ground. Measurement of the diameter at the height of the breast prevents the meter from calculating the width of the tree base, which would reflect the inaccurate diameter of the total tree.
Although the diameter tape actually measures the perimeter of the tree, it is easy to convert to the diameter. This is because the perimeter and diameter are connected by pi. However, the diameter tape does not provide quite accurate Measurements, as is assumed that the internal cross -sections of the tree are made of perfect circles. Any values obtained are therefore consideredana for approximation.
To measure the tree, the tree stem must first be prepared before using the diameter tape. The surface should be without nodes, branches or other obstacles. The circuit in which the tape will be used should be ground with a set or sandpaper. During this process, care should be used to prevent the tree damage.
The person should make sure that the diameter tape is on the breast. The tape should be perfectly at the level without reversing or reversing the most accurate reading. The side of the average should be at the top of the meter. When the zero number aligns with the end of the tape, the diameter is able to read the tape.
After measurement, the circuit can be converted to diameter. This is done by dividing the circuit by approximation of the pi unit, 3.14. Mathematicians recognize the use of the equation for the perimeter to solve the diameter.
Tree diameter rating in conjunction with height is important for detailsEcCI volume of tree wood. During the sale of a tree for pulp, timber or other purposes, its volume is necessary for correct prices and use. To estimate the volume of wood in stand trees, tables for tree volume are used. These tables show diameters and height diameters that indicate the diameters along the matrix to render a rapid visual display of the wood volume.
