Techflow Enterprises Executive Interview Questions, Process, and Tips

Fan efficiency can be calculated by dividing the useful power output by the input power.

• Fan efficiency = (Useful power output / Input power) * 100%

• Useful power output can be determined by measuring the airflow and pressure generated by the fan.

• Input power can be measured using a power meter or by multiplying the voltage and current supplied to the fan.

• Efficiency is typically expressed as a percentage, with higher value...read more

Bag House Area can be calculated by determining the air-to-cloth ratio and multiplying it by the gas flow rate.

• Calculate the gas flow rate in cubic feet per minute (CFM)

• Determine the air-to-cloth ratio (ACR) based on the type of baghouse

• Multiply the ACR by the gas flow rate to get the required baghouse area

• Consider factors like dust loading, pressure drop, and filter efficiency in the calculation

Yes, a fume extraction system removes harmful fumes and pollutants from the air to maintain a safe and healthy environment.

• Fume extraction systems use various methods to capture and remove fumes, such as hoods, ducts, and filters.

• These systems are commonly used in industries like manufacturing, welding, and chemical processing.

• They help protect workers from inhaling toxic gases and prevent the release of harmful pollut...read more

Lean phase and dense phase pneumatic conveying systems differ in terms of air-to-material ratio, conveying velocity, and material degradation.

• Lean phase pneumatic conveying system uses a high air-to-material ratio, while dense phase system uses a low air-to-material ratio.

• In lean phase system, the material is conveyed at high velocity, whereas in dense phase system, the material is conveyed at low velocity.

• Lean phase s...read more
