The nameplate of a reciprocating pump lists the following numerals as indicated 7" X 6" X 4". The diameter of the steam cylinder is __________.

🔍 Key Concepts

• How reciprocating pump dimensions are usually written on a nameplate (the order of the three numbers). • Difference between steam cylinder and water (pump) cylinder in a steam-driven reciprocating pump. • Which of the three listed values could reasonably be a stroke length rather than a cylinder diameter.

💭 Think About

• Ask yourself: in standard marine practice, when you see three numbers like 7" x 6" x 4" on a steam-driven reciprocating pump, what does each position (1st, 2nd, 3rd) normally represent? • Think about typical relative sizes: should the steam cylinder be larger, smaller, or about the same as the water cylinder, and how might that affect which number corresponds to which part? • Which number is most likely to represent the pump’s stroke (the distance the piston travels) instead of a cylinder diameter?

✅ Before You Answer

• Verify what the first number in a three-number pump designation usually corresponds to in marine engineering references. • Check that your choice for the steam cylinder makes sense compared to the water cylinder diameter and the stroke (the remaining two values). • Ensure you are not confusing the pump (water) cylinder diameter with the steam cylinder diameter; they are not necessarily the same.
