Water Evaporation Rate at 80°C, 1 atm

Click For Summary

Discussion Overview

The discussion revolves around calculating the evaporation rate of water at a temperature of 80°C under atmospheric pressure. Participants explore various factors that may influence the evaporation rate, including stirring speed and surface area.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant inquires about the evaporation rate while maintaining a temperature of 80°C at atmospheric pressure.
  • Another participant mentions the heat of vaporization of water as 40.65 kJ/mol and asks for additional details such as the amount of water, stirring speed, and surface area.
  • A third participant reiterates the heat of vaporization and provides specific parameters: stirring at 150 rpm, with a surface area of 50°C and a tank diameter of 2.5 meters.
  • A separate participant requests assistance in calculating the evaporation rate of water at 95°C, specifically in units of kg/hr.m².

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the evaporation rate or the specific calculations involved, as multiple queries and parameters are presented without resolution.

Contextual Notes

Participants mention various factors affecting evaporation, such as stirring speed and surface area, but do not clarify how these factors quantitatively influence the evaporation rate. The discussion includes different temperatures (80°C and 95°C) without a unified approach to the calculations.

Who May Find This Useful

This discussion may be useful for individuals interested in thermodynamics, fluid dynamics, or practical applications involving evaporation processes in engineering or scientific research.

For stirred, maintaining temperature at 80 and at atm pressure

thx ..
 
Engineering news on Phys.org
heat of vapourization of water is 40.65 kJ/mol. See if that helps.

Also; how much water? How fast are you stirring? Surface area of the water? 80°C or 80°F

my pleasure ..

Umm 150rpm , surface 50 C , 2.5m diameter of the tank
 
can someone help me how to calculate the evaporation rate of water at 95 degree celsius (kg/hr.m2 )
