Charge air LT
Total LT system
Flow LT at 36°C inlet and 44°C outlet
Jacket cooling
Charge air HT
Total HT system
Flow HT at 44°Cinlet and 80°C outlet
Total from engine
LT flow at 36°C inlet
LT temp. Outlet engine
(at 36°C and  string cooling water system)
Gas Data:
Exhaust gas flow
Exhaust gas temp.
Max. Allowable back press.
Air consumption
Starting Air System:
Air consumption per start
Heat Radiation:

Alternator
The stated heat balances are based on tropical conditions.
The exhaust gas data (exhaust gas flow, exhaust gas temp.
and air consumption). 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 (46-36)/(46-25)*00 = 53% of the original flow.
The HT flow will not change.
