Question

We have a system that must pump 195 GPM, at a height of 85 meters, and its losses by
accessories are 5% of their static load, please indicate the operating point and choose the impeller that
best fits between the options of the graph A, B, C, D and F, indicate what is the expected return
of this pump, which would be the expected consumption in Hp.
