Condenser water inlet & outlet temperature

hello guys,

For a cooling tower application how can i calculate the condenser water temperature inlet & outlet? i read that there is a book named black book i think they introduce many graphs with different flow capacities, inlet temp, outlet temp, wet bulb temp...... i wanna know how we can calculate the temperatures if somebody can help thanks. & does anyone has this book that have this graphs?

Thanks guys.

Total Heat of Rejection Kws = flow rate Litres per second x 4.2 Kj/kg x TD' K

TD' K = THR Kw / Litres per second x 4.2 Kj/kg

generally water temp rise is 5.5' C or 10' F
