2. Matla a Teko a Tloaelehileng (Maemo a Robeli)

Boemo ba 1: 0.325 kg = (Thupa ea Piston + Pane ea ho Bekha + Letsoho le Sireletsang + Boima ba Palo ea 1) = 3.187 N

Boemo ba 2: 1.200 kg = (0.325 + Palo ea 2 0.875 Boima) = 11.77 N

Boemo ba 3: 2.160 kg = (0.325 + Palo ea 3 1.835 Boima) = 21.18 N

Boemo ba 4: 3.800 kg = (0.325 + Palo ea 4 3.475 Boima) = 37.26 N

Boemo ba 5: 5.000 kg = (0.325 + Palo ea 5 4.675 Boima) = 49.03 N

Boemo ba 6: 10.000 kg = (0.325 + Palo ea 5 4.675 Boima + Palo ea 6 5.000 Boima) = 98.07 N

Boemo ba 7: 12.000 kg = (0.325 + Palo ea 5 4.675 Boima + Palo ea 6 5.000 + Palo ea 7 2.500 Boima) = 122.58 N

Boemo ba 8: 21.600 kg = (0.325 + Palo ea 2 0.875 Boima + Palo ea 3 1.835 + Palo ea 4 3.475 + Palo ea 5 4.675 + Palo ea 6 5.000 + Palo ea 7 2.500 + Palo ea 8 2.915 Boima) = 211.82 N

Phoso e lekanyelitsoeng ea boima ba 'mele ke ≤ 0.5%.

Sebopeho le Molao-motheo oa Mosebetsi:

Seteishene sa ho qhibilihisa phallo ke mofuta oa sesupa-tsela sa polasetiki se ntšang metsi. Tlas'a maemo a itseng a mocheso, sampole e lokelang ho lekoa e futhumatsoa ho fihlela boemong bo qhibilihisitsoeng ke sebōpi sa mocheso o phahameng. Sampole e qhibilihisitsoeng e ntan'o ntšoa ka lesoba le lenyenyane la bophara bo boletsoeng tlas'a mojaro oa boima bo behiloeng. Tlhahisong ea polasetiki ea likhoebo tsa indasteri le lipatlisisong tsa litsi tsa lipatlisiso tsa saense, "sekhahla sa phallo ea ho qhibiliha (boima)" hangata se sebelisoa ho emela ho phalla, ho teteana le thepa e meng ea 'mele ea thepa ea polymer boemong bo qhibilihisitsoeng. Seo ho thoeng ke index ea ho qhibiliha se bolela boima bo tloaelehileng ba karolo e 'ngoe le e 'ngoe ea sampole e ntšitsoeng e fetotsoeng ho bongata ba ho qhibilihisoa ka metsotso e 10.

Sesebediswa sa ho qhibilihisa (boima) phallo se bontshwa ke MFR, mme yuniti e le: digrama ka metsotso e 10 (g/min).

Foromo ke:

MFR(θ, mnom) = tref . m / t

Moo: θ —- mocheso oa teko

Mnom— - mojaro o tloaelehileng (Kg)

m —- boima bo tloaelehileng ba khaotso, g

tref —- nako ea litšupiso (metsotso e 10), S (lik'hilomithara tse 600)

t ——- nako ea karohano ea qetello, s

Mohlala:

Sehlopha sa disampole tsa polasetiki se ile sa sehoa metsotsoana e meng le e meng e 30, 'me liphetho tsa boima ba karolo ka 'ngoe e ne e le: ligrama tse 0.0816, ligrama tse 0.0862, ligrama tse 0.0815, ligrama tse 0.0895, ligrama tse 0.0825.

Boleng bo tloaelehileng m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (digrama)

Kenya sebakeng sa foromo: MFR = 600 × 0.0843 / 30 = 1.686 (ligrama ka metsotso e 10)
