FAQs in Mechanical Engineering Job interview:
1. Difference between ‘Thermodynamics’ and ‘Heat Transfer’:
- Thermodynamics mainly deals with the transfer of energy in the form of heat or work between systems and surroundings with other systems in the form of either heat or work in equilibrium conditions. When there is a change in one state, which was in an equilibrium state, and starting to change in other equilibrium states, this information helps to determine heat or work interactions due to this process. While
- Heat transfer deals with non-equilibrium heat exchange or transfer due to temperature gradient while in thermodynamics, during thermal equilibrium (No temperature gradient) no heat exchange is possible.

2. Difference between Pipe and tube
- There is always a debate about the differentiation between pipe and tube. The pipe is always designated by its Inside Diameter (ID) because the main purpose of the pipe is to carry fluid, while the
- The tube is always designated by its Outside Diameter (OD). The pipe’s thickness is sometimes called a schedule and the tube’s thickness is gauge.
- As per the tolerance basis, tubes require higher tolerances than pipe and tubes are costlier in manufacturing compared to pipe production.
3. Difference between Flywheel and Governor
The function of the flywheel is to store the energy/power produced during the power stroke of an engine and this stored energy is used during the remaining stroke to make the piston up and down during the working of the engine while the governor tries to control the speed of an engine due to variation in load. It does this work by reducing or increasing the amount of fuel passing through the engine.
