Question

Evaporation from pan is 24 mm. what is evaporation from waterbody

Answer 1

The evaporation pan of this standard set is made of stainless steel and has the

dimensions of a “class A“ evaporation pan, namely 54 mm (0 inches) in height

and 206 mm (47.5 inches) in diameter. The evaporation pan is installed on the

wooden support, which is set and levelled on the ground in a grassy location,

away from bushes, trees and other obstacles which obstruct a natural air flow

around the pan, thus representing open water in an open area.

Daily the result of evaporation and precipitation is measured within the still well,

by means of a high quality evaporation micrometer with a measuring range of

00 mm and an accuracy of 0.02 mm. This accuracy can be obtained because the

still well prevents rippling of the water surface
