mvura inoyerera nemupombi yemvura panguva imwe chete kubva mumvura
pombi.

Pe=ρ GQH/1000 (KW)

ρ——Kuwanda kwemvura inounzwa nepombi (kg/m3)
γ——Huremu hwemvura inounzwa nepombi (N/m3)
Q——Kuyerera kwepombi (m3/s)
H——Musoro wepombi （m)
g——Kukurumidza kwegiravhiti (m/s2).

2. Kushanda zvakanaka
Zvinoreva chikamu chehuwandu hwesimba rinoshanda repombi nesimba remubato, rinoratidzwa neη. Hazvigoneki kuti simba rese remubato riendeswe mumvura, uye pane kurasikirwa kwesimba mupombi yemvura.

Kushanda zvakanaka kunoratidza mwero unoshanda wekushandurwa kwesimba repombi yemvura, uye chiratidzo chakakosha chehunyanzvi uye chehupfumi chepombi yemvura.

η =Pe/P×100%

3. Simba remugodhi
Inozivikanwawo sesimba rekupinda. Inoreva simba rinowanikwa nepampu shaft kubva kumuchina wemagetsi, iro rinoratidzwa neP.

PShaft simba =Pe/η=ρgQH/1000/η (KW)

4. Simba rekufananidza
Inoreva simba remuchina wemagetsi unoenderana nepombi yemvura, iyo inomiririrwa naP.
