Type 1 water tender capacity, Type 2 capacity, and pumping rate

Type 1 water tender capacity, Type 2 capacity, and pumping rate

• A. Type 1: 1500 gallons; Type 2: 1000 gallons; Both must pump 200 gallons @ 100 psi
• B. Type 1: 2500 gallons; Type 2: 1500 gallons; Both must pump 300 gallons @ 200 psi
• C. Type 1: 2000 gallons; Type 2: 1000 gallons; Both must pump 250 gallons @ 150 psi
• D. Type 1: 2000 gallons; Type 2: 1200 gallons; Both must pump 250 gallons @ 150 psi

Answer: (C)

The question is about standard water tender classifications used in wildland operations: what the typical capacities are for Type 1 and Type 2 tenders and the common pumping rate at a given pressure. The established spec is that a Type 1 water tender carries about 2000 gallons, a Type 2 tender about 1000 gallons, and both are capable of pumping around 250 gallons per minute at 150 psi. This combination reflects how these tenders are used to supply water to engines during relay operations, providing enough volume and a steady flow at a manageable pressure. The option that matches 2000 gallons for Type 1, 1000 gallons for Type 2, and 250 gpm at 150 psi aligns with these standard values. Other options mix in nonstandard capacities or pump pressures/flows (for example, larger or smaller tank capacities or different pumping rates/pressures), which don’t correspond to the typical Type 1/Type 2 specs.
