In order to calculate the latent heat of steam, you will need to find the specific enthalpy of vaporization from a steam table. The specific enthalpy is the amount of heat required to change one kg of water into 1 kg of steam. Once you have found the specific enthalpy, you can use the equation: q = m * Δh.
q is the latent heat, m is the mass of water being turned into steam, and Δh is the specific enthalpy.
- Find the latent heat of vaporization for water at your steam table
- This will be listed in units of kJ/kg
- Find the boiling point of water at your steam table
- This will be listed in units of degrees Celsius or Kelvin
- Convert the boiling point to Kelvin if necessary
- Multiply the latent heat by the mass of water you have
- For example, if you have 0
- 5 kg of water and a latent heat of vaporization of 2,257 kJ/kg, you would multiply 2,257 by 0
- 5 to get 1,128 kJ total latent heat for your sample of water
How Do You Calculate Latent Heat of Steam?
In order to calculate latent heat of steam, we need to know the specific enthalpy of vaporization for water. This is the amount of heat that is required to change 1 kg of water from a liquid state at its boiling point (100°C) to a gas state at the same temperature. The value for this is 2,260 kJ/kg.
We can then use the formula:
latent heat of steam = specific enthalpy of vaporization x mass of water
For example, if we have 1 kg of water and we want to know the latent heat of steam required to vaporize it, we would plug in our values as follows:
latent heat of steam = 2,260 kJ/kg x 1 kg
Therefore, the latent heat of steam required to vaporize 1 kg of water is 2,260 kJ.
How Do You Find the Specific Heat of a Steam Table?
The specific heat of steam can be found in a steam table. There are different tables for different temperatures and pressures, so you will need to find the table that corresponds to the conditions under which you are working. Once you have found the correct table, look up the temperature and pressure that you are interested in and find the corresponding value of specific heat.
What is the Latent Heat of 1 Kg Steam?
The latent heat of steam is the amount of heat required to change 1 kg of water into steam. The value is different at different pressures, but the average value is 2.257 kJ/kg.
What is Hg in Steam Table?
The symbol Hg stands for the element mercury. The atomic number of mercury is 80 and it has an atomic mass of 200.59 amu. Mercury is a silvery-white metal that is liquid at room temperature.
It is sometimes called quicksilver.
Mercury vapor pressure is the pressure of mercury vapor in equilibrium with its non-vapor phases. All elements have a characteristic vapor pressure that depends on their heat of vaporization and ambient temperature.
For example, at room temperature, elemental mercury has a vapor pressure around 0.2 Pa or 2 nPa (nanopascal). This means that if you had a clean glass container filled with only mercury vapor and sealed so no outside gas could enter or escape, then over time the average pressure inside the container would equal 0.2 Pa thanks to atoms of mercury randomly entering and leaving the gas phase.

Steam Tables Calculator
The Steam Tables Calculator is a great online tool that can help you find the right information when you need to know the steam pressure, temperature, or other properties of water. You simply enter the desired value and then click on the calculate button. The calculator will do all of the work for you and provide you with the results in both metric and English units.
Steam Table Calculation Formula
You can use the steam table calculation formula to find the specific enthalpy of a substance at a particular temperature and pressure. This can be useful for finding the energy required to heat or cool a material, or for determining the properties of a substance in different states.
To use the steam table calculation formula, you need to know the following values:
The substance’s temperature in Kelvin (K)
The substance’s pressure in bars (bar)
The molar mass of the substance in kilograms per mole (kg/mol)
With these values, you can plug them into the equation: ???? = ????(???? + 273.15)(100000/????) where H is enthalpy, M is molar mass, T is temperature in Kelvin, and P is pressure in bars. This will give you the specific enthalpy of your chosen substance at that temperature and pressure.
Steam Table Temperature
The steam table is one of the most important pieces of equipment in a commercial kitchen. It allows chefs to cook food quickly and evenly, without having to worry about temperature control. The steam table is basically a large, hot plate that uses steam to heat food.
There are two types of steam tables: wet and dry. Wet steam tables use water to create steam, while dry steam tables use air.
Most commercial kitchens will have at least onesteam table, if not more.
They come in a variety of sizes and shapes, depending on the needs of the kitchen. Some common features of different models include:
-Wet or dry operation
-Built-in thermostat for temperature control
-Stainless steel construction for easy cleaning
-Insulated body to maintain consistent temperatures
-Removable water reservoir (for wet tables)
The most important thing to consider when choosing a steam table is its size. You want to make sure that it can accommodate the amount and type of food you’ll be cooking.
If you’re unsure about what size you need, it’s always better to err on the side of caution and get a larger model. Another important consideration is how many compartments your table will have. Most models have between two and four compartments, which allows you to keep different types of food warm at the same time.
Steam Table Engineering Toolbox
The Steam Table app from Engineering Toolbox is a great way to quickly look up the properties of saturated and superheated steam. It’s available for both iOS and Android, and it’s free!
Just select the desired output (temperature, pressure, enthalpy, etc.) and then input either the saturation temperature or pressure.
The app will then give you the corresponding values for both saturated and superheated steam. You can also switch between metric and imperial units.
This is a great tool for anyone who needs to work with steam, whether in engineering or in cooking!
Conclusion
If you want to calculate the latent heat from a steam table, there are a few things that you need to know. First, find the boiling point of water at your elevation. Next, find the enthalpy of vaporization for water at your boiling point.
Finally, use the steam table to find the specific enthalpy of saturated steam at your desired temperature. To calculate the latent heat, subtract the enthalpy of vaporization from the specific enthalpy of saturated steam.
