$1.$ You are asked to design irrigation system considering evapotranspiration for the area. You could use temperature method to estimate reference crop evapotranspiration $($ET$.).$

a$.$ Estimate crop evapotranspiration using given data $($Table $1)$ and crop factor for the area Kc$=0\mathrm{.}45.$

Climate adjustment factor $($b$)$ is function of bu and bn $(5$ points$).$

b$.$ Calculate discharge $($in m$\%)$ required for itrigation demand for given condition $($Table $2)(10$ points$).$

c$.$ Calculate energy required for the pump for a day, if water table is $5$ m below the ground surface.

Assume farm is almost level and pump is at the ground level. Pump efficiency$=$
