Australiaâs tallest trees can be found in the south-west of Western Australia in the Valley of the Giants. Giant tuart, karri, and rich red jarrah which live for up to 500 years can be found here.
Feeler gauge set. A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece.
Gauge is a descending scale, opposite the French scale of measurement which ascends with corresponding size. The higher the gauge size the smaller the tubing, for example, a 23G tubing has an OD/ID of 0.025âx 0.012â and 18G tubing has an OD/ID of 0.050â x 0.033â. Measuring a catheter based on a gauge measurement is common because laboratory personnel are familiar with standard needle sizes.
