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

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 ∆Mamb% = 0.0 and ∆T = 0.0, the corresponding calcula-
amb
tions will be as follows:
14,637 -1.5 0.0
M = 159,600 x x (1 + ) x (1 + )

T exh,M = 245 - 3.8 - 3.0 + 0 + 0 = 238.2° C
T exh,M = 234° C -/+15° C
The air consumption will be:
133,600 x 0.982 kg/h = 131,200 kg/h
131,200/3,600 kg/s = 36.4 kg/s
