Question

1) Uma bomba centrífuga, cujas características são apresentadas na Tabela 1, é utilizada para elevação da água (T=27°C) através do sistema representado pela Figura 4, composto por 8m de tubo de ferro fundido de 2,5" (Anexo 40) na sucção e 65m 2" (Anexo 40) na descarga. Considere as válvulas do tipo globo, totalmente abertas, e cotovelos padrão de 90°. Obter:

a) The value of the flow of water flowing through the pipeline
b) The power consumed by the pump for ƞ = 20%

1) A centrifugal pump, whose characteristics are presented in Table 1, is used to raise water
(T=27°C) through the system represented by Figure 4, composed of 8m of 2.5" cast iron pipe
(Schedule 40) in suction and 65m 2" (Schedule 40) in discharge. Consider the globe-type valves,
fully open, and standard 90° elbows. Get:
a) The value of the flow of water flowing through the pipeline
b) The power consumed by the pump for n = 20%
