A furnace uses preheated air to improve its fuel efficiency. Determine the adiabatic flame temperature when the furnance is operating at a mass air-fuel ratio of 16 for air preheated to 600 K. The fuel enters at 300 K. Assume the following simplified thermodynamic properties: Tref = 300 K MWFUEL=MWAIR=MWPROD = 29 kg/kmol cp, fuel =cp, air= cp, prod = 1200 J / kg-K
hf, air = hf, prod = 0 hf, fuel = 4x107 J/kg

2543 k

Explanation:

This problem can be resolved by applying the first law of thermodynamics

Determine the adiabatic flame temperature when the furnace is operating at a mass air-fuel ratio of 16 for air preheated to 600 K

attached below is a detailed solution

cp = 1200

answer:

i lost in getting someone back.

i learned that people are really two-faced and no matter how angelic someone appears they always have a devil side and that you cant trust anyone anymore no matter how dear they are to you.

if your wondering who it waz it waz mah still miss her tho
