🔍 Key Concepts

• Single-acting reciprocating pump displacement per stroke • Using cylinder diameter and stroke length to find volume per stroke • Applying volumetric efficiency and converting cubic inches/min to gallons/min (231 in³ = 1 gallon)

💭 Think About

• How do you calculate the volume of a cylinder using its diameter and stroke length? Write that out step by step. • Once you have cubic inches per stroke, how do you use strokes per minute and efficiency to find actual flow in cubic inches per minute? • After you have total cubic inches per minute, what single conversion factor do you use to change that to gallons per minute?

✅ Before You Answer

• Be sure to use radius (d/2), not diameter, in the cylinder volume formula. • Apply the 90% volumetric efficiency after you find the theoretical flow (don’t forget this step). • Use the correct conversion: 231 in³ = 1 gallon when turning cubic inches per minute into gallons per minute.
