Hi Shehan,
Thanks for sharing your design plan. It’s not necessary to discuss the specifics of the design in your report as long it’s fit for purpose. How did you decide on the tank volume? – the explanation behind this will likely spark interest when someone asks about your project. Suppose one of the reasons is the specimen capacity. In that case, it might be worth mentioning the approximate amount if you have this data.
I hope this helps.
Regards,
Jean
