(1). When there are two risers for fire hydrant system (stand pipe system), it is calculated 500gpm for total flow in h2x. But as per NFPA 14 additional 250gpm is also required. 500gpm is required due to 2 hose connections should be operated simultaneously. As such, total flow rate is should be 750gpm.

(2). Light hazard fire sprinklers hydraulic calculation is calculated without hose stream allowance. So additional 100gpm should be added for hose stream allowance as per NFPA 13.

(3). Ordinary hazard fire sprinklers hydraulic calculation is calculated without hose stream allowance. So 250gpm should be added for hose stream allowance as per NFPA 13.

And also add fire system as per all NFPA standards.

Kindly add these features to h2x.
