Steam is used to pre-heat an air stream before it is fed into a combustion chamber. Steam enters the well-insulated heat exchanger at 415 °C and 300.0 kPa and is isobarically condensed to a saturated liquid. The air enters at 45.0 °C and 125.0 kPa with a rate of 1050 L/s and must be heated to 255.0 °C. Assume air is an ideal gas with MW = 29 and Cp = 3.5*R.

Steam is used to pre-heat an air stream before it is fed into a combustion chamber. Steam enters the well-insulated heat
exchanger at 415 °C and 300.0 kPa and is isobarically condensed to a saturated liquid. The air enters at 45.0 °C and 125.0 kPa
with a rate of 1050 L/s and must be heated to 255.0 °C. Assume air is an ideal gas with MW = 29 and C₂ = 3.5*R.

Make sure to use the correct specific
volume for the exiting water stream.
