Commissioning and Operations Engineer Interview Questions and Answers

Velocity of water flushing, air blowing and steam blowing can be calculated using various formulas and measurements.

• For water flushing, velocity can be calculated using the formula Q/A, where Q is the flow rate and A is the cross-sectional area of the pipe.

• For air blowing, velocity can be calculated using the formula V = Q/A, where V is the velocity, Q is the flow rate and A is the cross-sectional area of the pipe.

• For steam blowing, velocity can be calculated using the formul...read more

Precommissioning and commissioning time can be reduced by proper planning, efficient execution, and use of technology.

• Develop a detailed commissioning plan with clear timelines and responsibilities.

• Ensure all necessary equipment and materials are available before starting commissioning activities.

• Use technology such as automation and simulation to streamline the commissioning process.

• Conduct thorough testing and inspection during precommissioning to identify and address any i...read more

Steam blowing flowrate can be calculated using various methods.

• Determine the volume of the piping system to be blown

• Calculate the required velocity of steam based on pipe diameter and length

• Determine the duration of the steam blow

• Use the formula Q = AV to calculate the required flowrate

• Consider safety factors and adjust flowrate accordingly

Target blowing parameters refer to the specific conditions required for blowing air into a target area.

• Target blowing parameters include air pressure, flow rate, and temperature.

• The target area may be a specific location within a larger system, such as a pipeline or tank.

• Parameters may vary depending on the type of material being blown, the distance of the target area, and other factors.

• Examples of target blowing applications include cleaning pipelines, removing debris from t...read more
