*An approximate value can be estimated by assuming all power entering the cabinet is converted to heat.
After calculating the total expected required heat load, use the charts in “Determining heat load capacities (on page 72)” to determine required water flow and pressure based on potential chilled water temperatures. The PSID must be measured prior to the cold water inlet/after warm water outlet. All water system equipment, materials, and installation must comply with any applicable construction codes and LAHJ.
Determining heat load capacities
The total airflow required by the equipment installed in each server rack must be compared with the total available supply from the
