Chilled Water Pump Head Calculation Fix ⭐ 🎉

Accurate chilled water pump head calculation requires:

[ H_equip = 7 + 4 + 3 = 14 , \textm ]

| Mistake | Consequence | Correction | |---------|------------|------------| | Adding static height in closed loop | Oversized pump, energy waste | Ignore elevation in closed systems | | Ignoring control valve pressure drop | Underflow at part load | Include fully open valve drop | | Using clean strainer K value | Fouling causes cavitation | Add 50% extra or specify basket pressure gauge | | Low pipe velocity | Higher pipe cost, air binding | Keep 1–3 m/s; > 4 m/s leads to erosion | | High velocity | Noise, erosion, high friction | Limit to 3 m/s for steel, 2.5 m/s for copper | chilled water pump head calculation
