Calculating Relative Humidity at 60°F

Click For Summary
SUMMARY

The discussion focuses on calculating the new relative humidity when the temperature is lowered from 70°F to 60°F. At 70°F, the maximum water vapor capacity is 8g/cubic foot, resulting in an actual water vapor content of 4.8g/cubic foot at 60% relative humidity. When the temperature decreases to 60°F, the maximum water vapor capacity drops to 5.8g/cubic foot. The new relative humidity can be calculated using the formula: (actual water vapor content / max water vapor capacity) x 100.

PREREQUISITES
  • Understanding of relative humidity and its calculation
  • Knowledge of water vapor capacity at different temperatures
  • Familiarity with basic thermodynamic principles
  • Ability to perform unit conversions and calculations
NEXT STEPS
  • Research the formula for calculating relative humidity

My brain is fried on other subjects. Help me!

Given: Max Water Vapor Capacity for Air @ 70 degrees F (21 deg. C)= 8g/cubic foot.

At 60% relative humidity, the actual water vapor content is 4.8g/cubic foot.

If the room temperature were lowered to 60 degrees F (16 deg. C) at which the max water vapor capacity is 5.8g/cubic foot, calculate the new relative humidity.

I would start by looking at where 60% (0.60) comes from -- then it will be easy to calculate from there.
