Pump Head Calculator
Calculate total dynamic head (TDH) for chilled water and hydronic pump systems.
Typical Equipment Pressure Drops
| Equipment | Head Loss (ft) |
|---|---|
| Chiller Evaporator | 10-25 |
| Cooling Coil | 15-30 |
| Control Valve (open) | 5-15 |
| Strainer | 2-5 |
| Heat Exchanger | 10-20 |
Design Guidelines
Velocity: 4-10 ft/s for steel, 3-8 ft/s for copper. Higher velocity = more noise.
Safety Factor: Add 10-20% to TDH for pump selection.
