diba po engr amg heat transferred sa isobaric process is mcpdelta t bakit po naging Q=change in enthalpy + work non flow sa isothermal po diba yan? thank you engr digs 🙌
35m²/min of air flows steadily through a compressor. It undergoes an isentropic change from 320C and 0.85 bar to 1.7 bar. The measured change in kinetic energy. is 2.5kJ/kg. Neglect changes in potential energy and determine (a) the change in internal energy; (b) the compressor power requirement.
Sa problem 3 po ndi po ba gagawin na absolute temperature yung 200 at 500 F. Thank you engineer
No need na sir. Kung kkunin mo lang dn naman ung change nilang dalawa, same lang po kalalabasan.
Thank you po Engr. more power po sa channel nyo!
Same naman po ng input sa calc
Engr. need po ba talaga iconvert into BTU kahit di hinihingi sa problem?
Pwde dn namang hindi na. Para less pagod heheheh
@@EngrJomDeGuia thank you po engineer!
sir, hindi na po ba need i-convert yung F to R? problem 3 isobaric
Change in Fahrenheit is equal to change in rankine kaya ok lng kht d na magconvert
@@EngrJomDeGuia tnx sir
engr. bakit po sa delta U, delta S, and Q ay Cv ang ginagamit and sa enthalpy naman po ay Cp. Ito po ay sa Isometric
Actually we can use Cp naman din. Convertible din naman ung Cv sa Cp.
So its up to you if gagamit ka ng Cp or Cv syempre maximize the given

Kapag isothermal un po talaga formula ♥️
Thank you Engineer
Hello engr. nalilito parin ako sa may bandang Enthalpy pano po naging k(∆u) pwde pa elaborate?
Oo nga asan galing po yung 1.4 na K
Ung 1.4 na K constant ng dry air un diba.
Sa problem no. 1 po bakit 1200 pi po lumalabas ty
Press S-D button of your scical para maging decimal yung sagot mu
Sa no. 3 pano po naging Cp = KR/K-1
Formula po yan derived

internal energy; (b) the compressor power requirement.
kailan po nag aassume ng 1lbm?
Pag walang bnanggit sa problem
kung metric naman po, 1 kgm po ba gagamitin?
Yes since ang pnakagnagamit naman pag SI and Metric is Kgm
okay thank you po Engineer!
