C'est mon petit doigt qui me l'a dit

I have the PQ curve of the DDC and the EHEIM 1250. They cross themselves at about 5.2 lpm. (first I estimated the PQ curve of the cascade from the cathar's results with the EHEIM 1250,1048 and MCP650 and I used it with the PQ curve of the DDC, and I saw 5.2 lpm like for the 1250)

I used the power/flow curve from rosco to determine the heat given to water by the pump (I used the same efficiency than cathar with the MCP650 alias D4) and found about 9W

5.2 lpm, 9W, same figures for the DDC and the EHEIM 1250, so same perfomances
