A fórmula para calcular a vazão de projeto para instalações hidráulicas de acordo com a NBR 10844/89 é: Qp = Ac x i x 0,001 Onde: Qp = Vazão de projeto (L/s) Ac = Área de contribuição (m²) i = Intensidade de precipitação pluviométrica (mm/h) Lembrando que a intensidade de precipitação pluviométrica pode ser obtida na NBR 7229.
