Exhaust gas data at specified MCR (ISO)
At specified MCR (M), the running point may be in
equations [4] and [5] considered as a service point
where P
S%
= 100, ∆m
s%
= 0.0 and ∆T
s
= 0.0.
For ISO ambient reference conditions where
∆M
amb%
= 0.0 and ∆T
amb
= 0.0, the corresponding
calculations will be as follows:

The air consumption will be:
76,180 x 0.982 kg/h = 74,809 kg/h <=>
74,809/3,600 kg/s = 20.8 kg/s
Final calculation
By means of equations [4] and [5], the final result is
found taking the exhaust gas flow M

and tempera-
ture T

from the ‘List of Capacities’:
