    Hi! Thank you so much for the videos, it’s been a great review before I take the exam in September. I just wanted to add; another shortcut would be to just divide the calculated cooling rate by the calculated compressor power to find the COP, so you don’t have to use the last equation.

      Hey! I'm glad you're finding the videos helpful!
      Interesting...Did not know that! Thank you for sharing this.
      Thermodynamics is one of those courses I wish I took in school haha. Really enjoyed making these videos. Keep doing your thing Aiden!

    where in the handbook v 10.3 do I find the equation W=m (deltah)? thank you for your videos!

      Hi Paola!
      This formula is not explicitly in the FE handbook. It's derived by conducting a steady flow energy balance.

      Page 148 from the long equation at the bottom, after cancelling all other terms (v/2, gz, & Qdot). Also, 149 has h_i = h_e + w , which is that deltah. Unfortunately, the handbook has the info spread all over, I'm struggling with it too. Good luck!
