Given the sprinkler system layout in Figure A$,$ calculate the flow and pressure required at point RN#$1($point B in Figure B$)$ without considering the impact of velocity pressures. Note that RN#$1($point B$)$ is the point at the bottom of the $1-$ft riser nipple as shown in Figure B$.$ Assume that the system is protecting an Ordinary Hazard Group $2$ occupancy with a $2000f{t}^2$ operating area and that K$-5\mathrm{.}6$ sprinklers are used. Schedule $40$ steel pipe with a C factor of $120$ is used.

Given the sprinkler system layout in Figure A$,$ calculate the flow and pressure required at sprinkler $4$ considering the impact of velocity pressures. Assume that the system is protecting an Ordinary Hazard Group $1$ occupancy with a $2000f{t}^2$ operating area.
