Final calculation
By means of equations [4] and [5], the final result <strong>is</strong>
found taking the exhaust gas flow M L1 and temperature
T L1 from the ‘L<strong>is</strong>t of Capacities’:

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:
M = 154,200 x exh,M 14,637 _____
