*
The TMS is a valved system and the “minimum required pressure differential” may not correlate with water
flow rates under all operating conditions. The “minimum required pressure differential” is required to
maintain adequate cooling-water flow under adverse operating conditions.
†
Based on water with a heat capacity of 4.18 kJ/kgK. Flow compensation must be made for coolants with a
lower value.
