Calculation of Condensate Amount

Plate 70713-42

Guiding values for condensation of water in the scavenge air cooler (drain from water
mist catcher), with full, unregulated, cooling water flow.

Example: 6L42MC, nominal rated: 8130 bhp.

For other MC engines – nominal rated or derated with nominal mean effective
pressure – the water condensation is approximately proportional to the MCR shaft
power.

It is rare to see values above 30 T/24h in this example.
