Maithan Alloys Interview Questions, Process, and Tips

Modes of heat transfer include conduction, convection, and radiation.

• Conduction: Heat transfer through direct contact between particles. Example: Touching a hot pan.

• Convection: Heat transfer through the movement of fluids (liquids or gases). Example: Boiling water.

• Radiation: Heat transfer through electromagnetic waves. Example: Feeling the warmth of the sun.

An addendum circle is a circle that is tangent to two other circles and intersects them at their points of tangency.

• Addendum circle is commonly used in gear design to determine the correct size of gears.

• It is tangent to two other circles, known as the base circles, and intersects them at their points of tangency.

• The addendum circle is larger in diameter than the base circles, allowing for the teeth of the gears to mesh

Rankine cycle is a thermodynamic cycle used in steam power plants to generate electricity.

• Rankine cycle involves four processes: compression, heating, expansion, and cooling.

• Steam is compressed in a pump, heated in a boiler to high temperature and pressure, expanded in a turbine, and then cooled in a condenser.

• The cycle is used in steam power plants to convert thermal energy into mechanical work, which is then used to
