Question
An acetylene (C2H2) torch has two modes of
operation. In the first mode, it is burned with
air at an equivalence ratio of 0.95 and a heat
release rate of 9.4 kW
Determine:
1. The mass flow rate of acetylene, in kg/s.
2. The mass flow rate of air, in kg/s.
3. The mass fraction of O2 in the products.
4. The adiabatic flame temperature, using
1600 and 2400 K as your guesses.
5. For the second mode, the acetylene (C2H2)
is burned with pure oxygen at an equivalence
ratio of 1.0. Determine the flame temperature
using 2800 and 3250 K as your guesses.
