Percent Excess Air Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percent Excess Air = ((Moles of Air Fed-Moles of Air Theoretical)/Moles of Air Theoretical)*100
% Excess Air = ((M_Fed-M_Theoretical)/M_Theoretical)*100
This formula uses 3 Variables

Variables Used

Percent Excess Air - Percent Excess Air means that amount of air supplied in addition to the theoretical quantity necessary for complete combustion of all fuel or combustible waste material present.
Moles of Air Fed - (Measured in Mole) - Moles of Air Fed is defined as total moles of air that is being fed to the process for combustion.
Moles of Air Theoretical - (Measured in Mole) - Moles of Air Theoretical is the exact amount of air required to provide the right amount of oxygen for complete combustion.

STEP 1: Convert Input(s) to Base Unit

Moles of Air Fed: 10 Mole --> 10 Mole No Conversion Required
Moles of Air Theoretical: 8 Mole --> 8 Mole No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

% Excess Air = ((M_Fed-M_Theoretical)/M_Theoretical)*100 --> ((10-8)/8)*100

Evaluating ... ...

% Excess Air = 25

STEP 3: Convert Result to Output's Unit

25 --> No Conversion Required

FINAL ANSWER

25 <-- Percent Excess Air

Net Calorific Value Based on Weight Percent of Hydrogen

Go Net Calorific Value = Gross Calorific Value-((Percentage Weight of Hydrogen*9*Latent Heat of Vaporization of Water)/100)

Net Calorific Value given Weight Fraction

Go Net Calorific Value = Gross Calorific Value-(Weight Fraction of Hydrogen*9*Latent Heat of Vaporization of Water)

Percent Excess Oxygen

Go Percent Excess Oxygen = ((0.21*(Moles of Air Fed-Moles of Oxygen Theoretical))/Moles of Oxygen Theoretical)*100

Net Calorific Value

Go Net Calorific Value = Gross Calorific Value-(Weight of Water Vapour*Latent Heat of Vaporization of Water)

Percent Excess Air

Go Percent Excess Air = ((Moles of Air Fed-Moles of Air Theoretical)/Moles of Air Theoretical)*100

Theoretical Air Requirement

Go Theoretical Air Requirement = Theoretical Oxygen Demand/0.21

Percent Excess Air Formula

Percent Excess Air = ((Moles of Air Fed-Moles of Air Theoretical)/Moles of Air Theoretical)*100
% Excess Air = ((M_Fed-M_Theoretical)/M_Theoretical)*100

What is Chemical Plant?

A chemical plant is an industrial process that manufactures chemicals, usually on a large scale. The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and/or separation of materials.

What is Chemical Process?

A chemical process is generally understood to be any discernable portion of chemical manufacturing during which feedstocks are acted upon to introduce a chemical change to the feedstock in order to convert it to a desired product.
