Flow Control

What is the definition of flow?

• A random and unpredictable event.

• The smooth and continuous movement of a substance or progression of events.

• A sudden and chaotic change in a system.

• The act of stopping or halting movement.

Name two types of flow mentioned in the content.

• laminar flow, turbulent flow

• steady flow

• viscous flow

• compressible flow

What is the importance of flow in industries?

• Flow is important in industries for optimizing processes, enhancing productivity, and ensuring efficient resource utilization.

• Flow has no impact on cost reduction.

• Flow is primarily concerned with employee satisfaction.

• Flow is only relevant in the service industry.

List the key elements of a flow system.

• Source, Medium, Pathway, Sink, Control Mechanisms

• Cause, Effect, Reaction, Outcome

• Input, Output, Feedback, Adjustment

• Energy, Force, Motion, Resistance

What characterizes laminar flow?

• Turbulent flow with chaotic fluid motion.

• Fluid moving in a circular pattern with high mixing.

• Irregular layers of fluid with varying velocities.

• Smooth, parallel layers of fluid with minimal mixing and steady flow.

How does turbulent flow differ from laminar flow?

• Turbulent flow is chaotic and irregular, while laminar flow is smooth and orderly.

• Laminar flow occurs only in gases, while turbulent flow occurs in liquids.

• Turbulent flow is always more efficient than laminar flow.

• Turbulent flow is always faster than laminar flow.

What is meant by steady flow?

• Steady flow is when fluid properties change rapidly over time.

• Steady flow refers to the movement of fluids in a circular path.

• Steady flow occurs only in gases and not in liquids.

• Steady flow is a condition where fluid properties at a point do not change with time.

Define unsteady flow in terms of flow rate.

• Unsteady flow occurs only in closed systems.

• Unsteady flow is when the flow rate remains constant over time.

• Unsteady flow is defined as flow where the flow rate varies with time.

• Unsteady flow is defined as flow where the velocity is uniform throughout.

What is one objective of flow control?

• To ensure data is sent in the correct order.

• To prevent data overflow at the receiver.

• To increase data transmission speed.

• To reduce the size of data packets.

What are the units of measurement for volume flow rate?

• Cubic centimeters per hour (cm³/h)

• Pints per second (pt/s)

• Barrels per day (bbl/d)

• Cubic meters per second (m³/s), liters per second (L/s), gallons per minute (GPM)
