Headloss calc #8

Closed FelixYuHengYang closed 6 years ago

FelixYuHengYang commented 6 years ago

@ethan92429 I am pretty sure I'm doing this wrong because I divided HL_Slider_Pipe by number of holes because I didn't how to calculate headloss through each of the holes Instead I divided headloss calculated as if all 20L/s were going through one hole by the number of holes. So it comes out to about 8.6 meters. Any pointers? headloss

HL_Slider_Hole=head_orifice(Slider_Hole_Diam, RatioVCOrifice, Q_Per_Hole) print(HL_Slider_Hole)

@ethan92429 I used the orifice equation from physchem. Each hole has a headloss of about .0079m according to this equation. With diameter of 1.5 inch, Q_Per_Hole of .2778 L/s found by dividing Q_Plant by maximum number of holes exposed, and ratio of vena contracta at .62.

See my github design file for more detail.
