Gostaria de perguntar a todos os especialistas do grupo. Recentemente encontrei um problema de seleção de ventilador, ou seja, não sei como calcular a resistência ao vento da tubulação e como determinar a pressão total do ventilador? Existe alguma fórmula de cálculo aproximada? Obrigado

Qual é a taxa de compressão do ventilador? Quão alta pode ser a pressão negativa de entrada do ventilador centrífugo?
