Pressure Drop
The expected waterside pressure drop at design flow is provided on the particular sales order form header. When
rated in accordance with AHRI-550, the actual pressure drop for clean tubes is permitted to be lower than or 15%
greater than the stated value.
To determine flow or waterside pressure drop at conditions other than sales order design, use the following relationship
to calculate the unknown parameter. Ensure consistent units of measure are used during calculation:
