Hikal Interview Questions, Process, and Tips

Q1. Type of heat transfer
Ans. 
Heat transfer is the movement of heat from one place to another due to a temperature difference.
• Three types of heat transfer: conduction, convection, radiation

• Conduction is the transfer of heat through a material without any movement of the material itself

• Convection is the transfer of heat through the movement of fluids (liquids or gases)

• Radiation is the transfer of heat through electromagnetic waves

• Examples: Conductio...read more

Q3. Type of distillation
Ans. 
Distillation is a process used to separate components of a liquid mixture based on differences in boiling points.
• Distillation involves heating the mixture to create vapor, then cooling the vapor to condense it back into liquid form.

• The components with lower boiling points will vaporize first and be collected, while the components with higher boiling points will remain in the liquid phase.

• Types of distillation include s...read more

Q5. Type of heat exchanger
Ans. 
There are various types of heat exchangers including shell and tube, plate, and finned tube.
• Shell and tube heat exchangers are commonly used in industrial applications due to their high heat transfer efficiency.

• Plate heat exchangers are compact and efficient, often used in HVAC systems and refrigeration.

• Finned tube heat exchangers are used when space is limited and increased surface area is needed for heat transfer.

Q2. What are the elements in MIS ? reasons for variance ?
Ans. 
Elements in MIS include data, information, systems, and processes. Variances can be caused by errors, changes in assumptions, or external factors.
• Elements in MIS: data, information, systems, processes

• Reasons for variance: errors, changes in assumptions, external factors

• Example: Variance in budgeted vs. actual expenses due to unexpected increase in costs

Q3. What is MHR ? how do you calculate it ?
Ans. 
MHR stands for Maximum Heart Rate. It is the highest heart rate an individual can achieve during exercise.
• MHR can be calculated using the formula: 220 - age

• For example, for a 30-year-old individual, the MHR would be 220 - 30 = 190 beats per minute

• MHR is used to determine target heart rate zones for exercise intensity

Q4. USE of MHR costing
Ans. 
MHR costing is a method of costing that assigns costs based on the actual resources used by a product or service.
• MHR costing stands for Machine Hour Rate costing, where costs are allocated based on machine hours used.

• It is useful in industries where machine usage is a significant factor in determining costs, such as manufacturing.

• MHR costing helps in accurately determining the cost of production for each unit based on ...read more

Q5. What is LHR need ? how do you calculate it and need of it ?
Ans. 
LHR stands for Liquidity-Asset Ratio, it is calculated to determine a company's ability to meet short-term obligations.
• LHR is calculated by dividing liquid assets by current liabilities.

• It helps assess a company's liquidity and ability to pay off short-term debts.

• A higher LHR indicates better liquidity and financial health.

• For example, if a company has liquid assets of $100,000 and current liabilities of $50,000, the L

Q2. What is distillation
Ans. 
Distillation is a process of separating components of a liquid mixture based on their different boiling points.
• Distillation involves heating a liquid mixture to vaporize the more volatile components.

• The vapor is then cooled and condensed back into a liquid, resulting in the separation of the components.

• The component with the lower boiling point will vaporize first and can be collected separately.

Q3. The selective boiling and subsequent condensation of a component in a liquid mixture.
Ans. 
Selective boiling and subsequent condensation is a process used to separate a specific component from a liquid mixture.
• Selective boiling involves heating the liquid mixture to a temperature at which the desired component vaporizes while other components remain in liquid form.

• The vapor is then condensed by cooling it down, resulting in the separation of the desired component from the mixture.

• This process is commonly use...read more
