Massachusetts 3rd Class Engineer Practice Exam

Question: 1 / 400

Which heading is NOT included in the five headings of steam tables?

Specific volume

Entropy

Kinetic energy

The heading that is not included in the five headings of steam tables is kinetic energy. Steam tables are designed to provide crucial thermodynamic properties of water and steam at various pressures and temperatures, primarily for use in thermodynamic calculations related to power generation and heat exchange processes.

In steam tables, the key properties typically include specific volume, entropy, enthalpy, pressure, and temperature. These properties are vital in understanding how steam behaves under different conditions, which is essential for engineers working with steam systems.

Kinetic energy, while an important concept in mechanics and thermodynamics, is generally not included as a specific heading in steam tables. This is because steam tables focus on properties that directly relate to phase changes, energy transfer, and the efficiency of steam systems rather than the energy associated with the motion of the steam itself. The kinetic energy of steam can often be assumed to be negligible for most engineering applications involving steam tables, as the focus is primarily on thermal properties.
