Pump/Fan Curve #2818

Closed koay9f closed 5 years ago

koay9f commented 5 years ago

General problems with the generation of the pump/fan curves by data. 1 - the equation doesn't match to the curve 2- the equation/generated curve doesn't match to the user input for order (order = 2 means the equation should have 0s for the coefficients of flow^5, flow^4, flow^3 (and not show these)

From user: image

Tried to replicate and got completely different (and still wrong) curve image

What you should get: image

last pic: what excel gets when you plug in the formula displayed in MEASUR image

So something really wrong is happening in "By Data" with respect to the order that is being used by the regression and possibly the regression calculation itself? or maybe the dataframe that the graph is using to make the curve.

Everything in the above looks good. For pump curve > By Equation Order is not matching the displayed fields image
