Assignment 3

1. Given a dry bulb reading of 85 degrees F and a wet bulb reading of 60 degrees F, determine relative humidity, dew point, absolute humidity, specific volume and enthalpy.

2 Define enthalpy.

3. Determine the amount of sensible heat needed to increase the temperature of air from 50 degrees F and 50% relative humidity to 90 degrees F.

Discussion 3

What is the difference between air conditioning and refrigeration?

How does an AC unit work?

What are the advantages of a steam heating system?

Why do hydronic systems work so well?
