1. Question 2. The attempt at a solution Now I'm not sure where to go next? Do I work out the local heat transfer coefficient at 1.2m or just the heat transfer coefficient? Using h = Nu × k/x or h = Nu × k/d Thanks, Sam.

I have been provided with this table, which shows enthalpy of combustion gases. I used these values when determining my flame temperature by calculating the heat content for each component = number of moles * enthalpy of component Then added the heat content per combustion gas to give me my...

Hi, Yes I have already calculated the flue gas composition, below is what I got: There is 10% excess air provided in combustion, this is why I have a small amount of oxygen in flue gas.

Thanks for the reply. I should have mentioned that a previous question asked me to calculate the flame temperature, this is why the temperature is so precise. I emailed my tutor with the following question: 'To my understanding I would require the specific heat capacity of the flue gases to...

Homework Statement If 5% of the heat available for steam production is lost to the atmosphere, determine the amount of steam raised per hour when the total flow of flue gases is 1400 kmol h-1. qmH = 1400 kmol h-1 Flue gas temperatures: Inlet = 1832°C Outlet = 300°C Water temperature: Inlet...
