Robert Fulkerson Cooling Tower Consultant

The design and test data required for a performance test are as follows:

The Cooling Technology Institute sells a little computer program they call "The Cooling Tower Tool Kit". The design data, test data and points from the performance curves are input to the program and it quickly calculates the test tower performance as a percentage of the design water flow the tower would be capable of cooling from the design hot water temperature to the design cold water temperature at the design wet bulb temperature when the fans are pitched to draw design fan hp. The test results can also be determined by cross-plotting the performance curves with a pencil. straight edge and French curves, With some loss of accuracy. It can also be done using MS Excel, but it is time consuming.
