I have a single data variable that varies with time. It is actually a pressure trace for a cylinder and increases to a peak over time then decreases. I want to find the the maximum pressure rise rate or maximum gradient of the curve. The curve has no equation and is just a set of time varying data points.
Is there a method for estimating the maximum gradient from the data?How do you calculate the maximum gradient of an unknown curve?
Well. You can keep drawing tangents until one which you find is the steepest. From your info, i have the idea that the curve is in the shape of a bell. So perhaps you can try drawing tangents at the mid-range of the curve.
Hope this helps=)
