(1) At the design chilled water temperature project a line until it intersects with the Server Discharge Temperature (SDT), read
off the cooling performance.
(e.g. 14°C projected up to 35°C SDT Line, reading across to 17.3kW.) All capacities based on water.

(2) Take the capacity, project a line to intersect the server discharge temperature (SDT) again and you can then read off the
air off temperature. (E.g. 17.3kW projected up to 35°C SDT line, read across to air off temperature; 24.5°C).
All capacities based on water.
