Fomura yekushandura pakati pekukurumidza kwekuyerera kwemvura mupaipi uye mwero wekuyerera kwemvura:
Mwero wekuyerera kwemvura wakaenzana nenzvimbo yepakati pemapaipi yakawedzerwa nekumhanya kwekuyerera kwemvura.
Rega mwero wekuyerera uve Q, dhayamita yemukati yepombi ive D, uye kumhanya kwekuyerera kwemvura kuve V. Zvadaro Q = π(D/2)²×V.
Kana chikamu cheQ chiri m³/h, chikamu cheD chiri m, uye chikamu cheV chiri m/s:
Q = π(D/2)²×V×3600 = 2827×D²×V (m³/h).
