Is it possible that first waiting time decreases and then after a certain point waiting time start increasing?

The sevice rate is fixed and the arrival rate is changing. As I am plotting the graph of arrival rate with respect to waiting time in queue.

Kunal .

Thank you Dr. Vladimir for clearing my query.

Sir, does the intensity of the electrons (10kV or 15 kV or 20 kV) used for SEM analysis affects the ettringite.. means its degradation or distortion or chemical changes?

Ettringite does not have visible beam damage at any voltage.
