🔍 Key Concepts

• Simplex double-acting pump: how many cylinder ends discharge each stroke? • Pump displacement per stroke: using bore (12") and stroke (8") to find volume moved each stroke. • Effect of slip (6%) on the theoretical discharge rate and converting cubic inches per minute to gallons per minute (gpm).

💭 Think About

• First, figure out how many discharge actions occur per stroke for a simplex double-acting pump and how that affects total volume per minute. • Calculate the theoretical volume per minute in cubic inches, then apply the 6% slip to find the actual volume. • Convert your final volume from cubic inches per minute to gallons per minute, remembering the cubic inches per gallon value.

✅ Before You Answer

• Be sure you are using the correct cylinder area formula (based on a 12" diameter) and multiplying by the correct stroke length. • Confirm how many times each revolution or stroke produces discharge for a double-acting pump (both ends of the piston). • Use the correct conversion: 1 gallon = 231 cubic inches, and then reduce by 6% slip (only 94% of theoretical flow).
