Water supply for Sprinkler system plus Outside Hose

I have a question about the selection of pump capacity and water tank size, 


As per my requirement, water demand for sprinkler system will be 1400gpm plus 250gpm for outside hose = 1650 gpm.


The selected capacity of Pump is 2000 gpm since no 1650 gpm is available as per UL listed and NFPA recommendation and duration of operation shall be 60mins.   


in this situation, my fire water tank should be sized to cater 2000gpm for 60mins of operation or 1650 gpm for 60mins operation. 


Please guide me in this regard.
