Color Drop Solution Interview Questions and Answers

Pumps and valves are used in various industries for fluid control. There are different types of pumps and valves for different applications.

• Types of pumps: centrifugal, positive displacement, axial flow, and jet pumps

• Types of valves: ball, gate, globe, butterfly, needle, and diaphragm valves

• Pumps are used to move fluids from one place to another, while valves are used to control the flow of fluids

• Centrifugal pumps are commonly used in water treatment plants, while positive di...read more

Centrifugal pumps work on the principle of converting rotational kinetic energy into hydrodynamic energy.

• The pump has an impeller that rotates and creates a centrifugal force, which pushes the fluid towards the outer edge of the impeller

• The fluid then enters the volute casing, where the kinetic energy is converted into pressure energy

• The pressure energy then forces the fluid out of the pump and into the piping system

• Centrifugal pumps are commonly used in industries such as oi...read more

Distillation is a process of separating components of a mixture based on their boiling points.

• There are two main types of distillation: batch distillation and continuous distillation.

• Batch distillation involves separating a mixture into its components in a single batch, while continuous distillation involves a continuous feed of the mixture.

• Other types of distillation include vacuum distillation, steam distillation, and fractional distillation.

• Vacuum distillation is used to s...read more

A packed bed column is a type of chemical reactor used for separation and purification processes.

• Consists of a cylindrical column filled with a packing material

• Fluid is passed through the column and interacts with the packing material

• Used in various industries such as chemical, pharmaceutical, and food processing

• Examples include distillation columns and gas absorption columns

Heat exchangers are devices that transfer heat between two or more fluids.

• Types include shell and tube, plate and frame, and air-cooled

• Shell and tube exchangers are commonly used in chemical and oil refineries

• Plate and frame exchangers are used in HVAC systems and food processing

• Air-cooled exchangers are used in power plants and natural gas processing

• Heat exchangers are also used in refrigeration and air conditioning systems
