Subros Engineer Trainee Interview Questions and Answers

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Compressors are used in various applications such as air conditioning, refrigeration, and gas turbines.

• They work by drawing in low-pressure gas and then compressing it to a higher pressure.

• Compressors can be classified into positive displacement and dynamic types.

• Positive displacement compressors use a piston or a rotating m...read more

Line balance refers to the equal distribution of work among different stations in a production line.

• Line balance ensures that each station in a production line has a similar workload.

• It helps in optimizing the efficiency and productivity of the production process.

• Line balancing techniques involve analyzing the tasks, cycle times, and capacities of each station to achieve optimal balance.

• An example of line balance is wh...read more

Lead time is the time it takes to complete a process from start to finish.

Types of current include direct current (DC) and alternating current (AC).

• Direct current (DC) flows in one direction and has a constant magnitude.

• Alternating current (AC) periodically changes direction and magnitude.

• Examples of DC include batteries and solar cells.

• Examples of AC include power grids and household outlets.

The frequency of alternative current is measured in hertz (Hz).

• The unit of measurement for alternative current frequency is hertz (Hz).

• Hertz is defined as one cycle per second.

• Common frequencies for alternative current include 50 Hz and 60 Hz.

• Higher frequencies, such as 400 Hz, are used in some specialized applications.
