1.2. Topshiriqni bajarish uchun misol
Misol. Quyidagi parametrlar asosida (xonani uzunligi l=4,0 m; xonani kengligi n=2,0 m; xonani balandligi h=3,0 m. yonilg‘I og‘irligi m=12 kg; yonish koefitsienti k=0,8; Ψ₁=0,1 to‘liq yonib ulgurmagan (CO hosil qiluvchi) uglerod miqdoriga javob beruvchi koefitsient; Ψ₂=0,15 ikkilamchi jaryonda CO hosil bo‘lishiga javob beruvchi koefitsient. T₁=40⁰C=313K; P=780mm.rt.st.) yog‘och, ko‘mir yoki boshqa turdagi yonilg‘ilarni yopiq xonada to‘liq yonishida xonananing qaysi balnadligida is gazini to‘planishini va is gazi qanday xajimni egallashini toping. Sodda qilib aytganda, uglerod oksidi yuqori qismida joylashgan va boshqa gazlar bilan aralashmaydi deb taxmin qilamiz.
Hisoblash: Barcha yoqilgan yoqilg'ini toza uglerod deb taxmin qilamiz. Uning miqdori yonish koeffitsienti bilan yoqilg'i massasi mahsuloti bilan aniqlanadi:
(1.5)
yoki

Yoqilg‘ini yonishi parallel holda ikkita jarayonda boradi:

(1.6)
(1.7)

Karbonad angidrid bir qismi cho‘g‘langan ko‘mir bilan ikkilamchi reaksiyaga kirishadi:

(1.8)

(1.6) da keltirilgan reaksiyada qatnashadigan uglerodning massasi quyidagiga teng:

(1.9)
yoki
(1.7) da keltirilgan reaksiyada qatnashadigan uglerodning massasi quyidagiga teng:
(1.10)
yoki

CO ni hosil qiluvchi uglerodning umumiy massasi quyidagiga teng:

(1.11)
yoki

Osonlashtirish maqsadida is gazini hosil bo‘lish jarayonini (1.7) dagi reaksiya bo‘yicha olib borilmoqda deb hisoblaymiz. Kimyoviy reaktsiyaga jalb qilingan massalarning nisbati asosida (1.1-vazifani echish uchun tushuntirishlarga qarang), hosil bo’lgan uglerod oksidining massasini topamiz.

(1.12)
yoki .
(CO ni molekular og‘irligini uglerod va kislorod atom og‘irligi yig‘indisidek topamiz; (1.7) tenglamadagi CO va C dan oldingi koeffitsientlar bir-birini bekor qiladi).
Normal sharoitlarda ushbu miqdordagi uglerod oksidi olinadigan hajm qo’yidagich hisoblanadi:
yoki 4,480 m³.
(CO ning bir mol massasi - 0,028 kg; normal sharoitda bir mol gaz egallagan hajmi - 22,4 litr, 1.1 vazifani echish uchun tushuntirishlarga qarang).
Birlashtirilgan gaz qonunining tenglamasiga binoan biz T = 313K darajasida uglerod oksidining haqiqiy hajmini topamiz:


(1.13)

Bu yerda

Xonaning maydoni

Uglerod oksidi bilan to'ldirilgan zonaning balandligini aniqlaymiz:

Ko‘rinib turibtiki xonada is gazi miqdori meyordan yuqori yoki

Javob: uglerod oksidi bilan to'ldirilgan zona 2,375 metrdan yuqori.
