2. 2.2 namunada yechib ko‘rsatilgan masala shartlari asosida ishlayotgan filtrpressda filtrlash jarayoni 25⁰S temperato’rasi olib borilganda ish unumorligi qanchagacha o‘zgaradi?
3. Temperato’rasi 40⁰S bo‘lgan 20 m³ paxta yog‘i bor. Ushbu miqdordagi yog‘ni 29430 Pa bosimda 4 soat mobaynida filtrlash uchun necha dona tipiq filtrpresslar kerak?
4. 30⁰S temperato’ra va 14750 Pa bosimda zig‘ir yog‘i filtrlash yuzasi 5 m² bo‘lgan laboratoriya filtrpressida filtrlanmoqda. Filtrpress 30 minut ishlaganda 480 l yog‘ olindi. Jarayonning filtrlash koeffisiyenti aniqlansin.
5. 50⁰S temperato’ra va 20000 Pa bosimda paxta yog‘i filtrlash yuzasi 7,6 m² bo‘lgan filtrpressda filtrlanmoqda. Agardi, 90 min vaqt ichida 3 m² yog‘ni filtrlash zarur bo‘lsa, jarayonning bosimi qancha bo‘lishi kerak?
6. Agarda, 3 ta siklda 42 m³suv tozalansa, plastinali filtrning o‘rtacha ish unumdorligini aniqlang. Har bir sikl filtrlash vaqti (3 soat) va filtrni tozalash va ishga tayyorlash vaqt (1 soat)lardan tashqil topgan.
7. Agar, filtrlash jarayonining tezligi w=0,00012 m³/ (m² x s) bo‘lsa, filtrning ish unumdorligi 4m²/soat bo‘lishi uchun 0,4x0,4 m o‘lchamli plastinkalardan necha dona kerak bo‘ladi?
8. Yuvish intensivligi 10dm³/(m²min); cho‘kma qatlam qalinligi 25 mm; yuvish suvi filtratidagi tuzning boshlang‘ich konsentratsiyasi 40 g/dm²; filtrlash vaqti 1 soat 10 minut bo‘lsa, yuvish tezligi qonstantasini aniqlang.
