OCR: BURGER Design Conditions Design Conditions determine the operating parameters for the cooling tower. EXAMPLE To cool a Circulating water volume (GPM) = 6000 specified GPM Entering hot water temperature (HWT) = 105 F Leaving cold water temperature (CWT) = 85 F From water entering Ambient wet bulb temperature (WBT) = 78 F the tower at T1 HWT In this example, the DESIGN CONDITIONS specify that the cooling tower provide a cooling RANGE of 20 degrees F. To water leaving tower RANGE = HWT - CWT at T2 at an APPROACH to wet bulb of 7 F. CWT APPROACH = CWT - WBT The problem is that the design conditions for a given tower are constantly changing 1 Continue 2 Previous 0 Main Menu
