#0183;#32;So I want to try to evaporate the water in a pyrex dish with a water and meth solution in it and do not feel like waiting days, preferably minutes instead. I was thinking that I could speed things up by inserting it into the oven at a little over 150f and seeing how that does. Is there any...
In the first simulation, the initial Ca +2 and SO 42concentrations are both mmol/L, and they remain exactly equal when the concentrations increase as water evaporates (the concentrations of SO 42 and Ca +2 overlap in the figure). The concentrations become fixed at M when the solubility of gypsum
How to calculate the energy required to evaporate water
The specific heat of dry gypsum has been artificially increased, over the temperature region of water evaporation, to values above the latent heat of evaporation, accounting for the heating rate
You can use [math]Q = mCpT[/math] to determine the amount of energy it would take to get water up to its boiling point (100 #176;C) and then use the Enthalpy of Vaporization to determine the amount of energy it would take to vaporize it. If you use t...

Any addition of heat will have to be to cementitious materials, 65C may be not enough to evaporate all the evaporate water, 105C is a If the soil contains organic matter or gypsum,
Sep 01, 2004#0183;#32;A simplified method is to convert the energy consumed to drive off water as additional specific heat of gypsum plasterboard. Thus, in heat transfer analysis only, (4) C p =C p, dry +C add, where C p,dry =950 J/kg #176;C and C add is the additional specific heat to drive off water, obtained as shown in Fig. 5.

May 02, 2019#0183;#32;The ovens cause the free water in gypsum panels to evaporate thus enabling the moisture content to be calculated by the difference in weight of the specimen before and after its exposure to heat.
Nov 12, 2016#0183;#32;Boil or evaporate? Water at room temperature 22 C must be raised to 100 C and heat of vaporisation added to become a gas. The specific heat of water is 4186 Joules/kgC. So 78 C rise requires 326,508 Joules per kg. The heat or Enthalpy of vaporisa...
So far, my understanding of water evaporating is the following: The higher the temperature, the higher the vapor pressure, therefore the faster water vaporizes. The rate of water boiling, assuming a constant boiling temperature, is dependent on the rate of heat transfer to the water, not the vapor pressure. At sea level, water boils at 100#176;c.

how to evaporate water from gypsum using heat. Increase the surface area by placing the water in a shallow tray. Blow (preferably warm) air over it by creating a crossdraught or using a fan. (Warmer air holds more moisture.)
#0183;#32;Heat of vaporization is the amount of heat energy required to change the state of a substance from a liquid into a vapor or gas. It is also known as enthalpy of vaporization, with units typically given in joules (J) or calories (cal).
Abstract:Heat and mass transfer through a gypsum board exposed to fire is simulated and compared to experimental data. The gypsum board is modeled as a porous medium with moist air in the pores. A dehydration front develops at the fire side and travels through the board, consuming energy and releasing water vapor.
Example Calculate heat required to evaporate 10 kg of water. The latent heat of evaporation for water is 2256 kJ/kg at atmospheric pressure and 100 o C. The heat required to evaporate 10 kg can be calculated as. q = (2256 kJ/kg) (10 kg) = 22560 kJ. Sponsored Links . Related Topics .
you want to evaporate 100 kg of water. we know, Cp( of water )= 1 kcal/ Latent heat of water = 540 kcal/kg. now, if we want to heat water from 20 to 100 deg C. Q = m*Cp*delT + m*lemda. Q = 100*1*80 + 100* 540. Q=8000 +54000. Q = 62000 kcal

In this study, the effect of moisture in gypsum plasterboard is to increase the specific heat of dry gypsum plasterboard over the temperature regions of water evaporation. Due to mass (moisture) transfer, this additional specific heat value will be higher than that of the latent heat of water evaporation.
