What is the approximate maximum available water indicated on supply graph 2 on plan F0.2?
The graph labeled as 'Water Supply Graph N2' presents a standard water supply flow test summary, which indicates the relationship between pressure (psi or kPa) and flow (gpm or Lpm) for a specific system or hydrant.
How to interpret the graph:
Static Pressure:
This is the pressure measured when there is no water flowing, shown at the highest point on the left side of the graph (indicated as approximately 100 psi or 689 kPa in this case).
Residual Pressure:
This is the pressure available when water is flowing at a specific rate. The residual pressure line decreases as flow increases, indicating that the pressure reduces when water is drawn from the system.
Maximum Available Water:
The maximum available water is the point where the system can deliver the highest possible flow (gpm) before the residual pressure reaches a critical minimum level, indicating the system's limit.
Flow at Maximum Available Water:
In this specific graph, the point marked as Maximum Available Water is where the flow reaches 1,980 gpm (7,495 Lpm). This is derived by following the flow axis (horizontal axis) until it intersects with the Maximum Available Water curve on the graph.
Why the Correct Answer is C (1,980 gpm):
By following the plotted line for residual pressure, the graph shows that the maximum flow attainable from the system is 1,980 gpm (7,495 Lpm) before pressure drops too low. This value represents the system's maximum water supply capacity under normal operating conditions.
This analysis is consistent with the flow rates displayed on the graph and matches the key markers labeled, which indicate the operational limits of the system.
NFPA Relevance:
In fire protection and water supply systems, understanding the maximum available water flow is essential for ensuring that sufficient water can be delivered in the event of a fire. This calculation is particularly relevant in the context of NFPA 20 (Standard for the Installation of Stationary Pumps for Fire Protection) and NFPA 25 (Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems), as these standards require that water supply systems are capable of delivering adequate flow to suppression systems under expected fire conditions.
What is the maximum common path of travel permitted in a sprinklered educational occupancy?
According to NFPA 101, Life Safety Code, the maximum common path of travel in a sprinklered educational occupancy is 100 feet (30 meters). The common path of travel refers to the distance occupants must travel before having two separate means of egress. The code provides this limit to ensure that occupants have a reasonably short distance to safety, enhancing the likelihood of safe evacuation in an emergency.
What percentage of wall area may be covered with art work in a sprinklered educational occupancy?
According to NFPA 101, Life Safety Code, in a sprinklered educational occupancy, no more than 20% of the wall area may be covered with artwork or teaching materials to minimize fire hazards and ensure safe evacuation routes (NFPA 101, Section 14.7.4). This percentage is intended to balance educational needs with fire safety requirements.

Which one of the following is a right given to a board of appeals?
The board of appeals does not have the authority to waive code requirements, set jurisdiction precedent, or withdraw a project. However, according to NFPA 1031, the board of appeals is typically granted the right to consider alternative methods or materials to those required by code, provided that they achieve the same level of safety. This is done to allow flexibility in the application of the code while maintaining safety and compliance.
The exact provisions for the board of appeals can be found in NFPA 1031 and the relevant local building and fire codes.
