hi all,
i wanna know that how can i determine the size generator fuel storage tank.
let suppose i have 3 generator and which capacity have 635kVA, 1250kVA and 700kVA...
and this generator will be operate 85%....
so its sum of kVA is 2585kVA and its 85% is 2197kVA and in kW is 1758kW.
Now i calculate my demand load is 1758.....
so now i wanna know that whats is size of my common fuel storage tank...?
as well as know that how many fuel will be consume at 5days......?

The generator spec sheets will tell you the fuel consumption rate.

The manufacturer should be able to tell you the fuel consumption for a given output power level.
Have you consulted the manufacturer ? have you done any google searching for the data for the generator(s) ?

You have all the make and model info I would have to assume, you havent told us any of that info

here i know that 1758kW is my demand load so
if may i convert 1758kW to btu/hour
and then required btu/hour convert to us gallon
so is it right way....
and if i find out us gallon / hour then i easily calculate for 5 days....
and then i easily look table of fuel storage tank in order to get dimension of tank
so is it right way or not..?

what Russ and I are trying to impress upon you ( well mainly me ;) hopefully Russ will agree with my assessment ) is that it depends on the fuel efficiency of the engine driving the generator... only the spec sheet will tell you that

eg. you may have one engine that burns 2 gallons an hour to produce 10kW from a generator where another engine may burn 5 gallons an hour to produce the same output

cheers
