What is the rated capacity of the water pump at 150 psi?

The rated capacity of a water pump is typically specified at a certain pressure, in this case, 150 psi. For many fire apparatus, including those used by Fort Lauderdale Fire Rescue, pump performance charts are established based on manufacturer specifications.

At 150 psi, a pump generally achieves a significant flow rate while still maintaining effective operational pressure. Given common specifications for fire pumps, a capacity of 1500 gallons per minute (GPM) aligns with the expected performance standards for a pump operating at that pressure. Fire departments often require high flow rates to ensure effective firefighting capability, especially in residential and commercial structures where water supply is critical.

Understanding this standard is essential for a driver engineer, as they must be familiar with the pump capacity to ensure adequate water supply during operations while also predicting the performance accurately based on pressure. The other options, although plausible at different pressures, do not reflect this specific scenario accurately, making 1500 GPM the correct choice for a pump rated at 150 psi.
