You know that pump designing we had to do for uni I told you about? Had the housings and impellers machined and did the testing...
I showed my impeller 2 design to 4th year fluid dynamics students and got "that won't pump" every time. Wouldn't even consider my reasoning behind it...
Impeller design 1: 6L per minute at 1500 RPM ~ 35 Watts (fairly standard energy consumption, high flow)
Impeller design 2: 4.8L per minute 1500 RPM ~ .5-1 Watt!!! (I couldn't believe results; tested it three times!) ;D ;D ;D
