Delta-T
The temperature rise of coolant across a cold plate or heat exchanger; it sizes flow rate and the warm-water loop.
Current numbers
~7.5–12 °Ctarget coolant delta-T across the TCS; cold-plate pressure drop ~20–55 kPa depending on plate and flow (no vendor-published NVL72 figure)
~1.25–2.0 L/min/kWDLC flow rule of thumb (PG25); ~7.5–12 °C coolant delta-T target across the TCS
~1.25–2.0 L/min/kWDLC flow rule of thumb (PG-25 coolant, ~7.5-12 C delta-T at the cold plate)
