Acetylene and oxygen are drawn from pressurized storage tanks and mixed together in an oxyacetylene torch in a ratio of 5.00 parts of oxygen per 1 part acetylene on a volume basis.
This mixture flows reversibly through the torch from 0.140 MPa, 20.0°C, to atmospheric pressure at 173°C, at which point it is ignited by the flame.
The mean surface temperature of the torch is 30.0°C, and it uses 0.100 m3 /s of oxygen at STP (0.101325 MPa, 20.0°C). Assuming ideal gas behavior, determine the work and heat transfer rates.
