Question

Calculate evaporation from water body if the evaporation from pan is 24mm and pan coefficient is 0.75 by placementstudy

Answer 1

Use the formula: ETo = E pan x K pan
ETo = Reference crop evapotranspiration 
E pan = Evaporation from Pan
K pan = Pan coefficient.

Therefore Evaporation from water body = 0.75 x 24 = 18mm

Hope this helps.

Answer 2

Answer: 18 mm

Given:

Evaporation from pan = 24 mm and pan coefficient = 0.75

Solution:

Formula for calculating the Evaporation from the water body is given by

$\mathrm{ET}=\mathrm{E} \times \mathrm{C}$

Where,  

ET = Reference crop evapotranspiration from the water body.

E = Evaporation from Pan

C = Pan Coefficient.

Thus, by Substituting the given values in above mentioned equation, we get

Evaporation from water body $=\mathrm{ET}=\mathrm{E} \times \mathrm{C}=0.75 \times 24=18 \ \mathrm{mm}$

Therefore, Evaporation from water body = 18 mm
