Here I am again little bit elaborating the same question (Question 1025446)
Tank is filled with water up to certain level not fully, when we place Spherical (PP)balls in to the tank
How many number of balls are required to form a layer above the liquid level?
Say

Tank dia. = 16000 mm
Spherical (PP) ball dia. = 50 mm
How many number of balls will be there at top of the liquid? To form a single layer/stack

Thank you.
Regards,
Pothula
