Delta_u and Delta_h Tips

You must quickly understand the difference between (U and u) and (H and h). Many students have a tough time knowing “when do I use u” and “when do I use h”? Check out this PPT presentation where this is explained and example problems are provided. Hint: Practicing engineers call both U and u “internal energy” and H and h “enthalpy” because of using them so much. That’s something that young engineers must pick up quickly and understand the differences.
