- Bophara ba ho kenya metsi: E khethiloe ho latela litlhaloso tsa pompo le litlhoko tsa moralo.
2.2 Impeller e potlakisa mokelikeli
- Impeller lebelo: Ka tloaelo ho 1450 RPM kapa 2900 RPM (liphetoho ka motsotso), ho it?etlehile ka moralo oa pompo le kopo.
- matla a centrifugal: Mokelikeli o potoloha ka lebelo le phahameng le tsamaisoang ke motlakase, 'me mokelikeli o potlakisoa ke matla a centrifugal.
2.3 Mokelikeli o phalla ka ntle ho 'mele oa pompo
- Moralo oa semathi: Mokelikeli o potlakileng o phalla ka ntle ho latela tsela ea ho phalla ea impeller mme o kena karolong ea volute ea 'mele oa pompo.
- Moqapi oa likhetho: Moralo oa volute o thusa ho fetolela matla a kinetic a mokelikeli ho ba matla a khatello.
2.4 Mokelikeli o tsoang 'meleng oa pompo
- Mokhoa oa ho nt?a metsi: Mokelikeli o fokotseha hape ka har'a volute ebe o fetoloa matla a khatello, 'me o nt?oa 'meleng oa pompo ka phala ea metsi.
- Bophara ba Outlet: E khethiloe ho latela litlhaloso tsa pompo le litlhoko tsa moralo.
3.mokhoa oa ho fetola matla
3.1 Phetoho ea matla a kinetic
- Ho potlakisa ho potlakisa: Mokelikeli o fumana matla a kinetic tlas'a ketso ea impeller, 'me lebelo la eona lea eketseha.
- Foromo ea matla a kinetic:( E_k = \frac{1}{2} mv^2)
- (E_k): matla a kinetic
- (m): Boima ba metsi
- (v): lebelo la metsi
3.2 Phetoho ea matla a khatello
- Ho fokotseha ha sekhahla: Mokelikeli o fokotseha ka sekhahla, 'me matla a kinetic a fetoloa matla a khatello.
- Equation ea Bernoulli( P + \frac{1}{2} \rho v^2 + \rho gh = \text{constant} )
- (P): Khatello
- ( \ rho ): ho teteana ha metsi
- (v): lebelo la metsi
- (g): ho potlakisa matla a khoheli
- (h): bophahamo
4.Litekanyetso tsa ts'ebetso
4.1 Phallo (Q)
- tlhaloso:pompo ea centrifugalPalo ea mokelikeli o fanoang ka nako ea yuniti.
- unit: Cubic metres ka hora (m3/h) kapa lilithara ka motsotsoana (L/s).

- unit: kilowatt (kW).
- Mokhoa oa ho bala:( P = \frac{Q \ linako H}{102 \nako \eta} )
- (Q): sekhahla sa phallo (m3/h)
- (H): Phahamisa (m)
- ( \ eta ): katleho ea pompo (hangata 0.6-0.8)
4.4 Sebetsa (η)
- tlhaloso: Matla a ho fetola matla a pompo.
- unit:peresente(%).
- bophara: Ka tloaelo 60% -85%, ho it?etlehile ka moralo oa pompo le kopo.
