Calculate cooling tower range and approach from hot water, cold water and entering wet bulb temperatures.
Range is how much the tower cools the water. Approach is how close the cold water gets to the outdoor wet bulb. An approach that grows over time at similar conditions often points to fouled fill, poor water distribution or a fan problem.
