Otto Cycle Sample

[@cyanidejoe6577]

Thank you for the help ful sample problems! 🎉🎉

I agree with you bro

maraming salamat, may diagram ka po sa PV at TS diagram?

[@musarapio_hha]

i have a question
can I use the ideal gas law, which is PV = nRT, to find the temperature and pressure at point 3, putting the data from point 2 into the isochoric process?
because the volume from point 2 to 3 doesn't change, when the piston is at TDC.
or the equation does not work for the otto cycle,

[@CBKCUSTOM]

you can use QA=mcv(t3-t2) to get T3

Diba po Sir nagchechange naman po ang Cv ng air base sa K nya.
Kasi magiging 0.171 lng po siya pag gagamitin ay k 1.4
Kaso po sa prob jan ang k 1.3 naman po

[@aldritzbryancabrera9752]

Correct. In short, use Cv = R / (k-1).

Can you answers this problem sir?
What is the change in efficiency if the compression ratio of an Air Standard Otto Cycle increases from 8 to 8.5?

[@JimboConstantino]

kunin mo yung efficiency ng dalawa and divide mo pR mKUH mo yung percent change between them. other solution is deduct the other.

[@k-lytesmigs5945]

@@JimboConstantino Sir pwede po ba makita kung pano i solve?

[@James-ko1hj]

Engineer question lang po sa Qadded, diba Cv = R/k-1 which is (1545/29)/1.3-1 supposedly based sa given mong air standard. So bakit ang gamit mo na Cv is 0.171 eh ang equal nun is (1545/29)/1.4-1. Ano po ang reason behind it?

[@James-ko1hj]

SANA MA NOTICE !!!!!!!!!!!!!!!!!!!!!!

Nerd ass comment bro

[@cyanidejoe6577]

Sir, please solve it on your own before asking engr to send solution to you!
