The clearance volume for a single stage compressor is defined as the space created between the __________.

🔍 Key Concepts

• clearance volume in a reciprocating (single-stage) compressor • Position of the piston at top dead center (TDC) vs bottom dead center (BDC) • All the small spaces where gas can remain when the piston is at the end of its compression stroke

💭 Think About

• First decide at which piston position clearance volume is measured: when the cylinder is most full of gas or when it is most compressed? • Think about all the places gas can still hide when the piston is as high as it can go—does it include spaces under valves and around the top ring? • Compare the options that mention TDC/BDC and ask: which one best describes the actual trapped gas volume left after the compression stroke?

✅ Before You Answer

• Verify that clearance volume is always associated with the end of the compression stroke (most compressed condition). • Check which answer choices include spaces under the valves and around the top piston ring, since gas trapped there is also part of clearance volume. • Eliminate any choice that uses BDC or ignores the small pockets where gas remains at TDC.

Question 1 of 27070

The clearance volume for a single stage compressor is defined as the space created between the __________.

top of the piston and bottom side of head, with the piston at BDC

piston and head, including the space around the piston to the top of the upper ring and under the valves, with the piston at TDC

bottom of the piston and bottom side of the head at TDC, regardless of upper ring location and valve placement

top of the piston and bottom side of the head at TDC as compared to that which exists between the top of the piston and bottom side of head at BDC
