Grasim Industries Interview Questions, Process, and Tips

The value of water pH indicates its acidity or alkalinity.

• Water pH is a measure of how acidic or alkaline the water is.

• The pH scale ranges from 0 to 14, with 7 being neutral.

• A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity.

• Pure water has a pH of 7.

• Different substances can affect the pH of water, such as pollutants or minerals.

40% of 800 is 320.

• Calculate 40% of 800 by multiplying 800 by 0.4.

• 40% of 800 = 800 * 0.4 = 320.

1 kilogram is equal to 0.001 metric tons.

• 1 kilogram = 0.001 metric tons

• To convert kilograms to metric tons, divide by 1000

• Example: 5 kilograms = 5 * 0.001 = 0.005 metric tons

pH scale is a measure of acidity or alkalinity of a solution on a scale of 0 to 14.

• pH below 7 indicates acidity, with 0 being the most acidic

• pH above 7 indicates alkalinity, with 14 being the most alkaline

• Pure water has a pH of 7, considered neutral

Water properties include cohesion, adhesion, high specific heat, universal solvent, and density anomaly.

• Cohesion: Water molecules stick to each other due to hydrogen bonding.

• Adhesion: Water molecules stick to other substances due to polarity.

• High specific heat: Water can absorb a lot of heat before temperature changes.

• Universal solvent: Water can dissolve many substances due to its polarity.

• Density anomaly: Water is mo

Air conditioning is a system that cools and dehumidifies air in an enclosed space to provide comfort.

• Air conditioning systems use refrigerants to cool the air.

• They remove heat and moisture from the air to create a more comfortable environment.

• Air conditioning can also help improve air quality by filtering out pollutants and allergens.

• Examples of air conditioning systems include central air conditioning units, window un

Lead time is the amount of time it takes for a product to be delivered after an order is placed.

• Lead time includes processing, production, and delivery time.

• It is important for businesses to minimize lead time to improve customer satisfaction.

• Example: If a company has a lead time of 5 days, it means it takes 5 days from order placement to delivery.

Lean manufacturing is a systematic method for eliminating waste within a manufacturing system while maximizing productivity.

• Focuses on continuous improvement

• Aims to reduce waste in all forms (time, resources, etc.)

• Involves empowering employees to identify and solve problems

• Uses tools like value stream mapping, 5S, and kanban

• Originated from the Toyota Production System

Kaizen activity is a continuous improvement process that involves all employees in making small changes to improve efficiency and quality.

• Kaizen is a Japanese term meaning 'change for the better'

• It focuses on making small, incremental improvements in processes and systems

• Kaizen involves all employees in the organization, from top management to frontline workers

• Examples of kaizen activities include implementing 5S metho...read more
