Pump Speed vs Capacity (\( \frac{N1}{N2} = \frac{q1}{q2} \)):

Where:

• \( N1 \) is the initial pump speed, in revolutions per minute (rpm).
• \( N2 \) is the final pump speed, in revolutions per minute (rpm).
• \( q1 \) is the initial pump capacity, in gallons per minute (gpm).
• \( q2 \) is the final pump capacity, in gallons per minute (gpm).
