Question 1
What is the primary purpose of a process flow diagram (PFD)?
A. To show equipment colors
B. To illustrate chemical reactions only
C. To show major equipment and process flow
D. To list maintenance schedules
Correct Answer: C
Rationale: A PFD provides a high-level overview of major equipment,
flow paths, and process relationships in a plant.
Question 2
Which device is used to measure fluid flow rate in a pipeline?
A. Thermometer
B. Flowmeter
C. Pressure gauge
D. Tachometer
Correct Answer: B
Rationale: A flowmeter is specifically designed to measure the rate of
fluid flow.
,Question 3
What does a pressure relief valve (PRV) do?
A. Increases system pressure
B. Maintains temperature
C. Releases excess pressure
D. Controls flow rate
Correct Answer: C
Rationale: A PRV protects equipment by releasing excess pressure when
limits are exceeded.
Question 4
Which unit is used to measure pressure in SI units?
A. Pascal
B. Joule
C. Watt
D. Newton
Correct Answer: A
Rationale: Pressure in SI units is measured in Pascals (Pa).
Question 5
What is the main function of a heat exchanger?
A. Store fluids
B. Mix chemicals
C. Transfer heat between fluids
,D. Measure temperature
Correct Answer: C
Rationale: Heat exchangers transfer thermal energy between two or
more fluids.
Question 6
Which hazard is most associated with confined spaces?
A. Noise only
B. Oxygen deficiency
C. High lighting
D. Low vibration
Correct Answer: B
Rationale: Confined spaces often have reduced oxygen levels, making
them dangerous.
Question 7
What is the purpose of a control valve?
A. Store pressure
B. Regulate flow
C. Increase viscosity
D. Measure density
Correct Answer: B
Rationale: Control valves regulate flow rate, pressure, or liquid level in a
process system.
, Question 8
Which instrument measures temperature?
A. Barometer
B. Thermocouple
C. Flowmeter
D. Hydrometer
Correct Answer: B
Rationale: Thermocouples are commonly used to measure temperature
in industrial systems.
Question 9
What does OSHA primarily regulate?
A. Product pricing
B. Workplace safety
C. Chemical formulas
D. Equipment design
Correct Answer: B
Rationale: OSHA sets and enforces workplace safety standards.
Question 10
What is cavitation in pumps?
A. Chemical corrosion
B. Air compression
C. Vapor bubble formation and collapse
D. Heat expansion
Correct Answer: C
