Question

Calculate the evaporation (mm) from a pound, if the pan evaporation is 45 mm, the pan coefficient is 0.70.

• A. 13.5
• B. 19.28
• C. 31.5
• D. 64.28

Answer 1

The correct option is C 31.5

$\therefore \text{Evaporatio from field}$
$=\text{Pan coefficient}\times \text{Pan evaporation}$
$=(0.70\times 45)=31.5\text{mm.}$
Hence, the evaporation from a pond is 31.5 mm.
