10+ Frankfinn Institute of Air Hostess Training Interview Questions and Answers

MS pipes are made of mild steel while DI pipes are made of ductile iron.

• MS pipes are cheaper than DI pipes.

• DI pipes are more durable and have higher tensile strength than MS pipes.

• DI pipes are used for water supply and sewage systems while MS pipes are used for gas and oil pipelines.

• DI pipes have a smoother inner surface which reduces friction and improves flow rate.

• MS pipes are prone to corrosion and require regular maintenance.

• DI pipes are more resistant to corrosion and ha...read more

SCADA stands for Supervisory Control and Data Acquisition. It is a system used to monitor and control industrial processes.

• SCADA systems collect data from sensors and other devices in real-time

• The data is then processed and displayed on a human-machine interface (HMI)

• Operators can use the HMI to monitor and control the process remotely

• SCADA systems are commonly used in industries such as oil and gas, water treatment, and manufacturing

• Examples of SCADA software include Ignitio...read more

Common defects in MS pipes include corrosion, cracks, leaks, and misalignment.

• Corrosion: Occurs due to exposure to moisture and chemicals, leading to rust and weakening of the pipe.

• Cracks: Can be caused by stress, improper handling, or manufacturing defects, compromising the structural integrity.

• Leaks: Result from faulty joints, damaged seals, or pipe degradation, causing fluid or gas to escape.

• Misalignment: Improper installation or movement can lead to misaligned pipes, affe...read more

The minimum thickness of OHT Raft depends on various factors such as load capacity, soil type, and seismic activity.

• The thickness of OHT Raft should be calculated based on the load capacity of the structure.

• The soil type and seismic activity of the area should also be considered while determining the minimum thickness.

• The minimum thickness of OHT Raft can vary from project to project depending on the above factors.

• Consulting with a structural engineer is recommended to determ...read more

I have extensive experience working with blast furnaces in previous roles.

• Managed daily operations of blast furnace including monitoring temperature and pressure levels

• Implemented safety protocols to ensure a secure working environment

• Collaborated with maintenance team to schedule repairs and maintenance tasks

• Optimized production processes to increase efficiency and reduce downtime

The density of CI pipes varies based on the size and thickness of the pipe.

• CI pipes have a density range of 6.9-7.8 g/cm³

• The density of CI pipes can be calculated using the formula: Density = Mass/Volume

• The density of CI pipes is affected by factors such as temperature and pressure

• The density of CI pipes is important for determining their strength and durability

Tolerance of top layers in highway engineering

• Tolerance refers to the acceptable deviation from the design specifications

• Top layers of a highway include asphalt, concrete, or other materials

• Tolerance is important to ensure the safety and durability of the road

• Factors affecting tolerance include climate, traffic volume, and materials used

• Regular maintenance and inspections can help identify and address tolerance issues

Crest is the highest point of a layer in a pavement structure.

• Crest is also known as the high point.

• It is important to ensure that the crest is properly designed and constructed to prevent water from pooling on the surface.

• The thickness of the layer at the crest should be sufficient to support the traffic loads.

• Examples of layers in a pavement structure include the subgrade, base course, and surface course.
