Pump Math Trainer

What's included:

• 300 unique practice problems, split evenly across four core categories: flow rate (GPM), friction loss, elevation, and full PDP scenarios
• 3 difficulty levels — Easy for learning the formulas, Medium for standard review, Hard for exam-ready precision with tighter tolerances and bigger hose lays
• Choose your session length — run 10 quick questions or the full 300, your call
• Step-by-step teaching on every question — before you answer, it walks you through the formula and the setup so you're learning the method, not just memorizing answers
• Voice narration — reads questions and explanations out loud, hands-free, so you can drill while you're doing other things
• Built-in reference sheet — toggle on a full page of friction loss coefficients, nozzle pressures, and formulas, visible on every question
• Instant, clear feedback — a green/red flag on every answer plus a running history strip so you can see your accuracy at a glance
• Live accuracy gauge — an actual analog PSI-style gauge tracks your running score as you go
