How to calculate the pressure drop in a rectangular pipe from volumetric flow rate?

I have been searching for the equation of calculating the pressure inside a rectangular pipe using volumetric flow rate but all I am finding is the Hagen–Poiseuille equation that calculates the pressure inside a cylindrical pipe: Flow rate=πr4(P−P0)/8ηl. Any idea?

How should I interpret these oxygen reduction impedance spectra?

  • Matthew BirdMatthew Bird
I am doing oxygen reduction in 0.1M KOH at a glassy carbon electrode coated with an electrocatalyst (with conductive carbon support, ethanol, nafion). When I do impedance at OCP I get the red Nyquist plot. When I apply an ORR potential I get the blue Nyquist plot.
I can't work out why I have the initial semi-circle (present both at OCP and during ORR) as it isn't in any literature examples. I can't find a circuit model that models these data well.
Any help would be appreciated.

I use 1M LiTFSI, 0.01M Li-BP in DOL DME solution to observe redox peak of LiBP.
But it shows only anodic peak and not cathodic peak, how can I solve it??
In this CV, I used WE-Sus foil. CE- Li foil, and two electrode system and scan rate is 50 mV /s.
Many papers say its cathodic peak is located around 0.7 V in similar conditions.
I attached the graph.

In Electrochemical CO2 reduction, it is always KHCO3 used as an electrolyte in H-Cell. Why it is the best choice compare to other electrolytes like Na2SO4, NaCl, KOH, etc.

The problem considered is that of finding a variable pressure gradient or forced motion of the pipe in a longitudinal direction which, at the time when it ceases to act, will have produced a prescribed distribution of velocity over the cross-section of the pipe.
