Actually in this case, Q_dot is "rate" of heat transfer, and q_dot is rate of heat transfer on a per mass basis. Basically just heat transfer divided by mass, with units of kj/kg in the metric system.
Q with dot is in KJ/s or KW it means that it is the heat added or removed per unit time, while the small q is in KJ/KG, it is the heat per mass of the system
you're life saver! I have hard time understand this chapter, thanks for your effort👍👍
Very informative and authentic, Bravo👏👏
Great video, thanks so much!
this is really helping,thank u sir
This is great! Thanks!
Good job
Really good
Thank you
For compressor and turbine, how it can use m * cp * t formular?
what is the difference between m with dot and m ?
M with dot is the mass flow, so derivative of mass difference over time
Whats the different between capital Q with dot and small q with dot?
Q_dot is Heat Transfer and q_dot is heat flux.

@@jamesturcotte3689 Cool thank you.

And what is the difference between m with dot and m ?
Promo SM 💪
great video. Thank you very much!
