Fitted normal distribution
Web2 days ago · Drop size distribution fitted more accurately with a log-normal distribution. Correlations for the prediction of N min and d 32 , have been developed in terms of Weber number, Morton number, hold-up, viscosity ratio, and power number of the impeller by using experimental data. WebA CDF or cumulative distribution function plot is basically a graph with on the X-axis the sorted values and on the Y-axis the cumulative distribution. So, I would create a new series with the sorted values as index and the cumulative distribution as values. First create an example series:
