Net Calorific Value Solution

STEP 0: Pre-Calculation Summary

Formula Used

Net Calorific Value = Gross Calorific Value-(Weight of Water Vapour*Latent Heat of Vaporization of Water)
NCV = GCV-(m*λ)
This formula uses 4 Variables

Variables Used

Net Calorific Value - (Measured in Joule per Cubic Meter) - Net Calorific Value means the specific amount of energy released as heat when a fuel undergoes complete combustion with oxygen under standard conditions.
Gross Calorific Value - (Measured in Joule per Cubic Meter) - Gross Calorific Value indicates how much energy can be released during the complete combustion of a given amount of fuel.
Weight of Water Vapour - (Measured in Kilogram) - Weight of Water Vapour is the form of a gas resulting from heating water or ice.
Latent Heat of Vaporization of Water - (Measured in Joule per Kilogram) - Latent Heat of Vaporization of Water is the amount of thermal energy that must be added to change a liquid to a gas.

STEP 1: Convert Input(s) to Base Unit

Gross Calorific Value: 400 Kilojoule per Cubic Meter --> 400000 Joule per Cubic Meter (Check conversion here)
Weight of Water Vapour: 15 Kilogram --> 15 Kilogram No Conversion Required
Latent Heat of Vaporization of Water: 2 Kilojoule per Kilogram --> 2000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

NCV = GCV-(m*λ) --> 400000-(15*2000)

Evaluating ... ...

NCV = 370000

STEP 3: Convert Result to Output's Unit

370000 Joule per Cubic Meter -->370 Kilojoule per Cubic Meter (Check conversion here)

FINAL ANSWER

370 Kilojoule per Cubic Meter <-- Net Calorific Value

(Calculation completed in 00.004 seconds)

What is Chemical Plant?

A chemical plant is an industrial process plant 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.

How to Calculate Net Calorific Value?

Net Calorific Value calculator uses Net Calorific Value = Gross Calorific Value-(Weight of Water Vapour*Latent Heat of Vaporization of Water) to calculate the Net Calorific Value, The Net Calorific Value formula is defined the amount of usable heat energy released when a fuel is burned under conditions similar to those in which it is normally used. The amount of heat spent in transforming the water into steam is not counted as part of net heat content. Net Calorific Value is denoted by NCV symbol.

How to calculate Net Calorific Value using this online calculator? To use this online calculator for Net Calorific Value, enter Gross Calorific Value (GCV), Weight of Water Vapour (m) & Latent Heat of Vaporization of Water (λ) and hit the calculate button. Here is how the Net Calorific Value calculation can be explained with given input values -> 0.37 = 400000-(15*2000).

FAQ

What is Net Calorific Value?

The Net Calorific Value formula is defined the amount of usable heat energy released when a fuel is burned under conditions similar to those in which it is normally used. The amount of heat spent in transforming the water into steam is not counted as part of net heat content and is represented as NCV = GCV-(m*λ) or Net Calorific Value = Gross Calorific Value-(Weight of Water Vapour*Latent Heat of Vaporization of Water). Gross Calorific Value indicates how much energy can be released during the complete combustion of a given amount of fuel, Weight of Water Vapour is the form of a gas resulting from heating water or ice & Latent Heat of Vaporization of Water is the amount of thermal energy that must be added to change a liquid to a gas.

How to calculate Net Calorific Value?

The Net Calorific Value formula is defined the amount of usable heat energy released when a fuel is burned under conditions similar to those in which it is normally used. The amount of heat spent in transforming the water into steam is not counted as part of net heat content is calculated using Net Calorific Value = Gross Calorific Value-(Weight of Water Vapour*Latent Heat of Vaporization of Water). To calculate Net Calorific Value, you need Gross Calorific Value (GCV), Weight of Water Vapour (m) & Latent Heat of Vaporization of Water (λ). With our tool, you need to enter the respective value for Gross Calorific Value, Weight of Water Vapour & Latent Heat of Vaporization of Water and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Net Calorific Value?

In this formula, Net Calorific Value uses Gross Calorific Value, Weight of Water Vapour & Latent Heat of Vaporization of Water. We can use 2 other way(s) to calculate the same, which is/are as follows -

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