LT charge air
Total LT system
LT flow at 36°C inlet and 44°C outlet*
Jacket cooling
HT charge air
Total HT system
HT flow at 44°C inlet and 80°C outlet*
Total from engine
LT flow from engine at 36°C inlet
LT outlet temperature from engine at 36°C inlet
(-string cooling water system)
Gas data:
Exhaust gas flow
Exhaust gas temperature at turbine outlet
Maximum allowable back pressure
Air consumption

The stated heat balances are based on 00% load and tropical
condition.
The mass flows and exhaust gas temperature are based on ISO
ambient condition.
* The outlet temperature of the HT water is fixed to 80°C, and
44°C for the LT water.
At different inlet temperature the flow will change accordingly.
Example: If the inlet temperature is 25°C then the LT flow will
change to (44-36)/(44-25)*00 = 42% of the original flow.
The HT flow will not change.
