A) Bernoulli’s equation
B) Hagen-Poiseuille equation
C) Fourier’s law
D) Newton’s law of viscosity
Answer: B
Explanation: The Hagen-Poiseuille equation describes the pressure drop and flow rate for laminar flow in a cylindrical pipe, based on the fluid’s viscosity and the pipe’s dimensions.
4. Question: What is the purpose of a control valve in a process control system?
A) To store excess fluid
B) To regulate the flow rate of a fluid
C) To generate electricity
D) To measure temperature
Answer: B
Explanation: A control valve adjusts the flow of fluids in response to signals from a controller, maintaining desired process variables like pressure or level.
5. Question: In mass balance calculations, what does a steady-state system imply?
A) Mass is accumulating in the system
B) Mass inflow equals mass outflow
C) The system is at rest
D) Temperature is constant
Answer: B
Explanation: In a steady-state system, the rate of mass entering equals the rate leaving, resulting in no net accumulation or depletion of mass over time.
6. Question: Which type of pump is most suitable for handling viscous fluids like oil?
A) Centrifugal pump
B) Positive displacement pump
C) Axial flow pump
D) Jet pump
Answer: B
Explanation: Positive displacement pumps move a fixed volume of fluid with each cycle, making them effective for high-viscosity fluids that centrifugal pumps struggle with.
7. Question: What is the key factor in determining the efficiency of a chemical reactor?
A) The color of the reactor material
B) The residence time of reactants
C) The external appearance of the reactor
D) The weight of the catalyst
Answer: B
