A power plant is situated at an altitude having an ambient air at 96.53 kpa and 23.88 0c. flue gases at a rate of 5 kg/sec enter the stack at 200 0 c and leaves at 160 0c. the flow gases gravimetric analyses are 18 % co 2 , 7 % o 2 , and 75 % n 2 . calculate the diameter of the stack (in meters) for a driving pressure of 0.20 kpa. note: the actual velocity is 40 % of the theoretical velocity.

Answer:

A power plant is situated at an altitude having an ambient air at 96.53 kPa and 23.88 0C. Flue gases at a rate of 5 kg/sec enter the stack at 200 0C and leaves at 160 0C. The flow gases gravimetric analyses are 18 % CO2, 7 % O2, and 75 % N2. Calculate the diameter of the stack (in meters) for a driving pressure of 0.20 kPa.

Note: The actual velocity is 40 % of the theoretical velocity.
