For how many oz of fluid would you count for 8oz of milk, broth based soup, papaya juice with pulp, rice porridge and tapioca porridge? Ty

Depends. On portions. 8 oz for the water and broth, maybe 6 for the nectar ( total minus pulp), and whatever water or liquid was used to make porridge, e.g. 1 cup liquid to 1/2 cup oats, likewise for pudding.
Also drink water. . It is hard to tell how many ounces of water in milk, soup, juice and other food. I would say if you are concerned about drinking enough liquid, drink more water. If you are concerned about consuming a lot of liquid due to health problem, talk to your doctor or nutritionist/ dietician about how much you should be consuming fluid a day.
