About two years in, this is a quick montage of tricks from one take, and attempts at double and vertical.

    0:53 Only reversible! adiabatic processes are isentropic (ΔS=0). In typical adiabatic processes, there is no heat transfer across the system's boundaries (ΔQ=0)

    At 5:54 I think your air standard cycle represents the T-S cycle in wrong way because the T3 is the maximum temperature where as T4 is temperature less than T3 but greater than T2. By the way I like the line "Believe me I am Engineer😂😂" I know every engineer's hardships. And love your content ❤❤. And can we join in insta.

    Think u can try to add some explanation on the equipment involved in the carnot cycle (compressor, turbine etc.) and try to explain heat pump and refrigerator, and also try explain some concepts like why the curve for adiabatic is steeper than the isothermal line, why adiabatic processes are also isentropic etc, I did spend some time to read it up on the internet just now :) Anyway very good job and clear explanation, pronunciation is nice and clear n u seem very passionate about the subject!

    Thank you. I’m having a hard time with entropy. Can anyone tell me what constant entropy means? Thanks

    • @carultch
      @carultch 2 роки тому

      The short answer is that entropy is a measure of the disorder in a system. A process happening with constant entropy, means a reversible process with no heat transfer. Idealized processes that expand and compress fluids, are examples of constant entropy processes. That is an oversimplified explanation, but the idea is that time's arrow always points to either an increase in entropy, or constant entropy. You cannot destroy entropy; you can generate it, keep it the same, discard it to your surroundings, or bring it in from your surroundings, but you cannot destroy it without time running backwards. Entropy enters a system with heat transfer, and the amount of entropy is proportional to the heat transferred and inversely proportional to the Kelvin temperature at which it transfers. The formula is delta S = delta Q/T, for a constant temperature heat addition process. So an adiabatic and reversible process will have no change in entropy. A reversible process, is an idealized version of a process that doesn't destroy any entropy. The process is possible in both directions. Examples of such processes that could be reversible in the upper limit of perfection are: Motors and generators Turbines and compressors Compression and expansion of a gas in a cylinder with no heat transfer at the same time Heat transfer across an infinitesimal temperature difference Electric current through superconductors The following processes are inherently irreversible: Throttling valves Sudden expansion of a gas Heat transfer across a finite temperature difference Mixing Any process involving frictional heating or ohmic heating
