Dear Prof. Joshua Meyer, I just started watching your lecture videos. Your lectures are making a lot of impact in my life and teaching skill. I teach Heat and Mass Transfer in department of Mechanical Engineering, Rivers State University, Port Harcourt, Nigeria. In fact my students are really enjoying the lectures. Could you please kindly arrange the whole lectures in a series of chapters (playlists )or topics divided according to the topic because I didnt follow from begining. I will be very grateful because it be of great help to me and the students. I will also be grateful if you can assist me to get the textbook of Cengel and Ghajar. Thank you' my email is tonileo.ust@gmail.com

in the Nusselt number sample problem, the unit of k value of the air is watt,/ m K . while the unit of h is watt/sq m C, d o we have to convert K to C,
so means that, we need two temperature which hot and cold in order to use heat exchangers. is it possible to use pvc or silicon material for heat exchangers??
Thank you Mr. Josua Meyer... Keep explaining and making the future engineers dreaming and helping us improving the world... You sir are a MVP (Most Valuable Player) :)
Sir, I'm confused with one concept of thermal resistance where you've taken the resistance due to convection and radiation parallel to the resistance due to conduction. Can you help me out with this doubt?
Professor, I think you may have meant semi infinite bodies instead of lumped ones at 1:48 seconds, right? Thank you very much for your content here in youtube!
Thanks professor for the video. I just have a question about tube shell heat exchanger. Is there any formula which links the dew pression within the condenser (hot fluid) and the temperature of the cooling fluid?
What will happen if the same pipe as described in the example is in a room which has walls with a different temperature from the air. What does it change in the radiation? Thanks
+Stephanos Stavrinides i think the radiation in this case will be from the pipe to the wall temp and room temperature will be irrelevant to the radiation, we will just consider it for the convective heat transfer
i think assumption of taking the wall temperature is constant is false. it cant be. becz the in order to maintain constant rise in fluid temperature the delta T should decrease.
