Virchow Biotech QA QC Engineer Interview Questions and Answers

The power of a pump can be calculated using the formula: Power = (Flow rate x Head) / Efficiency

• The power of a pump is determined by the flow rate, head, and efficiency

• Flow rate is the volume of fluid passing through the pump per unit time

• Head is the height difference between the inlet and outlet of the pump

• Efficiency is the ratio of the actual power output to the power input

• The formula to calculate power is: Power = (...read more

Air flow in HVAC ducting can be calculated using the formula Q = AV

• Q = air flow rate in cubic feet per minute (CFM)

• A = cross-sectional area of the duct in square feet

• V = air velocity in feet per minute (FPM)

• Air velocity can be measured using a pitot tube or an anemometer

• Duct sizing and layout can affect air flow and should be considered in calculations

A reactor can be installed by following a few steps.

• Choose a suitable location for the reactor

• Prepare the foundation for the reactor

• Install the reactor vessel and associated equipment

• Connect the piping and electrical systems

• Test the reactor for proper functioning

Commissioning of a reactor involves a series of tests and procedures to ensure safe and efficient operation.

• Pre-commissioning checks and inspections

• Functional testing of equipment and systems

• Testing of safety systems

• Fuel loading and reactor startup

• Performance testing and optimization

• Final acceptance testing

• Documentation and training

• Regulatory approval

• Examples: Pressurized Water Reactor (PWR), Boiling Water Reactor (BWR

Condensers are used to convert high-pressure vapor into liquid form.

• Condensers are used in various industries such as power plants, refrigeration systems, and chemical processing plants.

• They help in increasing the efficiency of the system by reducing the pressure and temperature of the vapor.

• They also help in recovering valuable materials from the vapor, such as water in a power plant.

• Examples of condensers include she...read more
