Bechtel Interview Questions, Process, and Tips

General Chemical engineering question related to fluid mechanics and thermodynamics.

Q1. Type of pump, cavitation, pump.curve
Ans. 
Different types of pumps include centrifugal, reciprocating, and rotary pumps. Cavitation occurs when low pressure causes bubbles to form in the pump, leading to damage. Pump curve shows the relationship between flow rate and head.
• Types of pumps: centrifugal, reciprocating, rotary

Q1. Expansion stress formula
Ans. 
Expansion stress formula calculates the stress caused by thermal expansion or contraction.
• Expansion stress formula is given by: ΔL/L = αΔT, where ΔL is the change in length, L is the original length, α is the coefficient of thermal expansion, and ΔT is the change in temperature.

• The formula can be used to calculate the stress caused by thermal expansion or contraction in piping systems.

• The formula assumes that the mater...read more

Q3. Sustain stress formula
Ans. 
Sustain stress formula calculates the maximum allowable stress for a given material under sustained loading.
• Sustain stress formula is used in piping stress analysis to determine the maximum allowable stress for a given material under sustained loading.

• The formula takes into account the material's yield strength, ultimate tensile strength, and safety factor.

• Sustain stress formula is expressed as S = (Sy/FS) + (Su/FS) * ...read more
