How do we know that the refrigerant at 50 C is superheated vapor and not saturated liquid/vapor or mixture ?
Thanks for the video 👍
Sir will you explain how you got the last question?😢
I love your videos sir
The question asks for energy transfer by mass not seconds, basically specific energy... Shouldn't the answer therefore be in a per kg format?
If it's reversible ONLY does that mean S2 - S1 = Q/T ?? Because Sgen would be zero at that point.
yes, correct. Sgen is a measure of irreversibility. So a reversible heat transfer would be S2-S1 = Q/T
Would you say that entropy IS conserved in an ideal system? Reversible system?
This is a turbine, Work OUT of the system is positive, Q is negative
If you write your equation as Q-W, then yes, work out is positive. If you write your equation as Q+W, then work out is negative. It is just a matter of preference. Most thermodynamicists like Q-W and doing it like you said. Most physicists (and me!) like Q+W. Do you see that we would end up the the same equation?
That is so well said in the beginning, light bulb!!
Do you ever solve for Entropy change with Cpln(T2/T1) - Rln(P2/P1)??? Or is it further down the list?
# 7 LOLOL, You have some weird values for R-134a, but problem seven is solved just like you did it, find Q = S2 - S1 X Temp... then U2 - U1... ah you know the rest.... but those values you're throwing out there for this substance are suspect. LOL
I am using the property tables from Cengel and Boles. The property tables from Moran and Shapiro look slightly different, but in the same ballpark. Honestly, this is just a problem (and solution) striaght from the Cengel and Boles textbook. I would double check your tables. engineering.wayne.edu/mechanical/pdfs/thermodynamic-_tables-updated.pdf
#6 S = 3450 BTU/ Tsat @ 20 pisa which is 3450 BTU/688 R = 5.01 ish (This is quick way, if it was isothermal it'd be 3450 / 530 R but it's not so you have to divide by the sat temp at constant P of 20 psia)
#5 0.07182 is completely wrong, Sf at 101.3 kPa = 0.8690... also S1 = 1.8625 not 1.0625.
again, I'm not sure what R134 tables you are looking at. The tables from Cengel and Boles show what I've got in the video.
R134a at 50C and 1200 kPa is 426.84 kJ/kg and hf (at saturation liquid) 45C is 264.11 kJ/kg.
again, double checking my tables, but I've got that R134a at 50C and 1200kPa is 278.28 kj/kg. And hf at 45 would be the average of 117.34 and 114.30.
I’m using Cengel and Boles property tables. You can look in table A13 and A11 www.dropbox.com/scl/fi/l5ir7947mx69qm3i1bq1t/Property-Tables-Appendices-1-and-2.pdf?rlkey=ombvp8i0xpxmllg31fdts1y8p&dl=0
or just h out at 300K
using Cv(T2 - T1) doesn't work here, you HAVE to look up 3051.6 in the table for "U" instead.
You should ask how fast is the water falling, since PE = KE... 39.57 m/s is the answer.
I used the method of centroid composite body and got roughly the same volume but not exactly. Thank you for your videos, very good explanation.
jhh🎉
potentential lmao
🤦🏻♂️ four years and 224k views and I never noticed that until now!
@@engineeringdeciphered you're the best! <3
Thanks a lot !!!
thank you so much
Those who were questioning themselves about the formula:👇 ∆P=pgh........ΔP (is the pressure difference (in Pa or N/m²)).
No 7. S1 is wrong.
This is the best video I’ve watched on combined loading and not to mention, I haven’t understood the right hand rule for YEARS because no one has ever explained it well to me, but this video cleared up all my confusion on everything. Everything I questioned that I didn’t even understand enough to question was explained so well! I wish I found this video sooner
I'm a engineering student from Brazil and your videos are helping me a lot in my thermodynamics exams, thanks man!
where you get that 2.5 in I section?
And if there was another two force member connected to B? Would we just add another force to the point B in the body diagram, in the direction of the beam added?
Why fgc is not producing any momement
Just wondering what textbook you use in this series! Just want to know how to compare my organize my studying against the "Fundamentals of Engineering Thermodynamics (9th Edition) Moran, Shapiro, Boettner, Bailey" used by my teachers :)
I use thermodynamics, an engineering approach, by Cengel and boles
@@engineeringdeciphered Thank you so much, love your videos!
guys please suggest me a channel with similar teaching style for the topics he didnt upload. thanks
But why don’t you calculate for you u in number e
Appreciate your effort. 2:31 Wanna ask, isn't ther another force on pin B, which is F_ab. ?
And ofc there are forces on pin C, we didn't consider :)
how can students afford these notes
how u find hf
Covid vibes 💀
ims till struggling :(
0:10 in the moment equation the last term, shouldn't it be (10) *(12.5). Because the distributed force has its centre at 12.5 ft away from point B.
yes, you are correct. It should say 10*12.5. That will give you the Ay of 9.5 kips.
Can we buy or download the formula sheet?
You have organized your material extremely well. Thank you!
To know if the bolts/cylinder is on Tension or Compression: draw a FBD of the object alone it self after cutting it.
Do you have a playlist on System Dynamics? I really enjoyed your dynamics explanations and would greatly appreciate if you had any resources for Dynamic Systems as well
What did you plug in exactly for the V= 105.4
I believe that would come from v^2/2 - 2^2/2 = .002(2356.7)^2/2 solve that for v.
Its nice that these are broken into short clips.. gives you a sense of accomplishment each time and makes you want to keep going onto the next video!
I wish you were my professor for this class, actually enjoyable. My professor is death by powerpoint and theory. 0 real practice problems in class. Its awful.
can you please share your assigned homework problems for thermodynamics. just problem number and book edition are more than sufficient. thank you
please do thermo 2
Broooo I has this last semester I forgot wt I studied I am scared wt will happen to me 😭
Thanks a lot sir.
i might got confuse but why , when i use the right hand rule for the Mz , I get my finger to curls , the other way ? ;-; . like my thumb pointing upwards , it suppose to go from left to right isnt it
