Q$2.$ Dingman Chapter $6,$ problem $6\mathrm{.}2$

$[15$ points$]$

$2.$ The table on the following page gives the hourly air temperature, $T_a,$ relative humidity, $RH,$ wind speed, $u(2m),$ and water$-$surface temperatures, $T_s,$ for Lake Hefner, Oklahoma, on $3$ May $1951.$ The lake area is $9\mathrm{.}4k{m}^2.$ Compare the average evaporation rate for that day via the mass$-$transfer approach by

a$.$ calculating the evaporation rate for each hour and averaging the results; and

b$.$ averaging the values in the table and using those averages in the mass$-$transfer equation.
