How much air is required for complete combustion of 1kg of carbon?
1 kg of carbon requires 8/3 kg of oxygen for its complete combustion; therefore C kg of carbon will require C x 8/3 kg of oxygen which is equivalent to 2.66C kg of oxygen (considering upto two places of decimal).
How much kg air is required for complete combustion of 1kg by mass?
Approximately 14.5 kg of air is required for complete combustion of 1 kg of gasoline.
What is the weight of air required for combustion of 4 kg of coal?
All Answers (4) 1 kg coal is 1/12 kmol coal (pure C assumed), needs 1/12 kmol O2 for combustion, or 1/12 * 100/21 kmol of air. This is roughly 0.4 kmol of air/hr, or 11.5 kg of air/hr.
How do you calculate air needed for combustion?
Divide room volume (Step 1) by total/1000 (Step 2). If less than 50, additional air is needed. If greater than or equal to 50, no additional air is needed.
What is weight and volume of air required for combustion of 2kg of carbon?
Calculate weight of air needed for complete combustion of 2kg of coal containing C=70\%, H=10\%, O=10\%, N=5\% and remaining ash….
Combustion reactions | Weight of O2 required(kg) |
---|---|
2) H2+12O2 → H2O | 0.1 × 16 1 = 0.8 |
How much oxygen is needed for complete combustion?
Oxygen reacts with a fuel to produce water and carbon dioxide. A large volume of air is needed for complete combustion because the air we breathe is only 21\% oxygen. In an exothermic reaction, heat and light are released.
How many liters of O2 at STP are needed to complete the combustion of 39 grams of liquid benzene?
Explanation: Hence 84 litres of O2 at STP are needed to complete the combustion of 39g of liquid benzene.
What will be the volume of O2 gas at STP which is required for complete combustion of 7.8 g acetylene?
According to reaction, At STP; 1 mole of acetylene that is 22.4L require 5/2 moles of oxygen that is 52×22.4 = 56L for complete combustion.
For complete combustion, 1 kg of carbon requires (8/3) kg of oxygen. Therefore, the amount of air required for complete combustion of 1kg of carbon is 11.59 kg.
What is the volume of oxygen required for complete combustion of coal?
So the volume of oxygen required for the complete combustion of 1000- g of coal is= 1000/12 = 83⅓ x 22.4- LITRES of oxygen. We know Air is mixture containing 78\% NITROGEN, 21\% Oxygen and 1\% of other gases such as CO2, Argon etc.,.
How much oxygen do you need for combustion?
You have 1000/12 moles of carbon so that would need 1,000/12 x 22.4 litres of oxygen. BUT air is only 21\% oxygen so you’ll need 1,000/12 x 22.4 x 100/21 litres of air. This would be your answer in theory. BUT you are unlikely to get complete combustion without an excess of air being available. So you’ll need more air.
What is the mass of the combustible elements in the fuel?
As we know in the ultimate analysis of fuel we determine the mass of various combustible elements in the fuel. In 1 kg of fuel: Carbon is 0.83 kg, hydrogen 0.05 kg, oxygen 0.02 kg and sulphur 0.002 kg. Minimum quantity of air required for complete combustion of 1 kg of fuel is given by:
