Alf Engineering Interview Questions, Process, and Tips

There are three types of flow studied in fluid mechanics.

• Laminar flow

• Turbulent flow

• Transitional flow

An orifice is a small opening or hole through which fluid or gas can flow.

• Orifices are commonly used in various applications such as in pipes, nozzles, and valves.

• They are used to control the flow rate of fluids or gases.

• The size and shape of the orifice determine the flow characteristics.

• Orifices can be circular, rectangular, or any other shape depending on the application.

• Examples of orifices include the nozzle of a ...read more

Steady flow refers to the continuous flow of a fluid without any changes in its properties or characteristics.

• Steady flow occurs when the fluid properties such as velocity, pressure, and temperature remain constant at any given point in the flow field over time.

• In steady flow, the flow rate of the fluid remains constant.

• Examples of steady flow include the flow of water through a pipe with a constant pressure difference...read more

Quality Tools or 7QC tools are a set of techniques used for quality control and improvement in various industries.

• Check sheets: Used to collect and analyze data in a systematic manner.

• Pareto chart: Helps identify the most significant factors contributing to a problem.

• Cause and effect diagram (Fishbone diagram): Used to identify and analyze potential causes of a problem.

• Histogram: Represents data distribution visually.

• S...read more

FMEA is required to identify and prioritize potential failure modes in a process or product.

• Helps in identifying potential failure modes and their effects

• Prioritizes failure modes based on severity, occurrence, and detection

• Aids in developing preventive actions to mitigate risks

• Improves overall process or product reliability and quality

• Commonly used in industries like manufacturing, healthcare, and automotive

Drafting SOP involves outlining step-by-step procedures to ensure consistency and efficiency in operations.

• Identify the process to be documented

• Outline each step in detail

• Include responsibilities, timelines, and quality standards

• Review and revise SOP regularly

• Seek input from relevant stakeholders

• Provide training on SOP implementation

Failure Mode, Effect and Cause (FMECA) is a systematic method for identifying potential failure modes of a system, analyzing their effects, and determining their causes.

• FMECA helps in identifying potential failure modes of a system

• It analyzes the effects of these failure modes on the system

• It determines the causes of these failure modes

• FMECA is used in industries like automotive, aerospace, and manufacturing

Bending is the process of deforming a material along a straight axis, while forming is the process of shaping a material into a desired form.

• Bending involves applying force to a material to change its shape along a single axis.

• Forming involves shaping a material into a desired form, which may involve bending as one of the steps.

• Bending is often used in metalworking to create angles or curves in a piece of metal.

• Forming...read more
