British Paints Business Analyst Interview Questions and Answers

The optimum diameter of a pump depends on various factors such as flow rate, head, viscosity, and efficiency.

• The diameter should be selected based on the required flow rate and head of the system.

• Higher viscosity fluids require larger diameter pumps to reduce frictional losses.

• Efficiency of the pump increases with larger diameter impellers.

• The diameter should also be selected based on the available space and cost const...read more

Stream balance inside distillation column is crucial for efficient separation of components.

• Stream balance refers to the equal distribution of feed and product streams across the column.

• Imbalance can lead to poor separation efficiency, flooding, or tray damage.

• Factors affecting stream balance include tray design, liquid and vapor flow rates, and column diameter.

• Techniques such as tray hydraulics and computational fluid...read more

Designing a distillation column for binary mixtures involves determining the number of trays, feed location, and reflux ratio.

• Determine the boiling points of the components

• Calculate the minimum reflux ratio

• Choose the number of trays based on the desired separation

• Determine the feed location based on the composition of the feed

• Design the reboiler and condenser

• Consider the pressure drop across the column

The number of lifts required in a building can be estimated based on factors like building size, occupancy, and usage patterns.

• Consider the size and height of the building - taller buildings may require more lifts

• Take into account the number of floors and units in the building

• Factor in the expected occupancy and usage patterns - a residential building may require fewer lifts than a commercial building

• Consider peak usag...read more

The lift takes approximately 30 seconds to go from top floor to bottom.

• The time taken for the lift to go from top floor to bottom can vary depending on the speed of the lift and the number of floors.

• On average, a lift takes around 20-30 seconds to go from top floor to bottom in a standard building.

• Factors such as the weight of the passengers, maintenance of the lift, and any stops in between can also affect the time ta

Revenue is calculated year over year by comparing the total revenue from one year to the next using historical data.

• Calculate total revenue for each year

• Compare total revenue from current year to previous year

• Use historical data to track revenue trends

• Consider factors like seasonality, market trends, and economic conditions

• Formula: Year-over-Year Revenue Growth Rate = ((Current Year Revenue - Previous Year Revenue) / P
