• ### Chapter 4 - Determination of ETo

The ET o calculation can be done by hand with the help of a calculation sheet, or by means of a computer. ET o can also be estimated from the evaporation loss from a water surface. The procedure to obtain ET o from pan evaporation and the coefficients for different types of pans are presented in this chapter. Penman-Monteith equation

• ### Evaporation in Average Year - Maps - …

Maps for each month use a 15 year average (1985-1999) to show what average annual evaporation is like. The rate at which evaporation takes place is influenced by temperature, sunshine, wind and the humidity of the air – with temperature and sunshine being the most important.

• ### Chapter 1 - Introduction to evapotranspiration

Evaporation is the process whereby liquid water is converted to water vapour (vaporization) and removed from the evaporating surface (vapour removal). Water evaporates from a variety of surfaces, such as lakes, rivers, pavements, soils and wet vegetation. ... This chapter introduces the user to the need to standardize one method to compute ET o ...

FACTOR OF EVAPORATION Water enters the boiler at 225°F. The boiler pressure is 100 psi and the boiler water temperature is 338°F. The latent heat is 881 Btu. What is the factor of evaporation? FE = SH + LH / 970.3 FE = SH + LH / 970.3 FE = ((338 - 225) + 881) / 970.3 FE = 1.02 Where, FE factor of evaporation SH sensible heat LH latent heat
