Topic: ampere hour calculation

We have 10 tanks which are fed by 10 pumps from two tanks.Each nickel tank ia set at an ampere of 200 amps .If it is a continuous reel  plating process  at 6 meter per minute how do you calculate the brightener¬†

1.based on area per tank sq dm /tank and total area plated per hour in sq dm..we can calculate ampere hour from the data input

. 2.another nethod is that 200 amps per cell per hour multiplied by 10 gives you 2000 ampere hour

Can you advise the correct ampere hours and whuch calculation we use,, 

There is a confusion in calculation and output.

This question looks rudimentary..Can you use the parameter from method 1 and get the same result of advise
