What is the difference between flow process and non flow process?
Flow process takes place in open system & non-flow process takes place in closed system.
What is the difference between an open circuit and an open aev?
This is copied from Section 6.11, Question 8 in "Modern Refrigeration and Air Conditioning." The answer is (B), "The open circuit prevents flow. The open AEV allows flow to occur." Although a bit obscure, the answer is correct because, within the context of an electrical circuit, an "open circuit" (i.e. disconnected wire) would prevent the flow of electrical current. Within the context of a refrigeration circuit, an open AEV (automatic expansion valve) would permit the flow of refrigerant into an evaporator coil to provide cooling.
Will the current flow in a circuit in which there is a gap between two wires?
No, the current will not flow in a circuit with a gap between two wires, as a complete circuit is necessary for current to flow. The gap creates an open circuit, preventing electrons from moving through the circuit. Current requires a continuous path to travel, and without that connection, there is no flow.
What happens if the switch is open?
If the switch is open, current does not flow.

The open channel flow has a free surface whereas the pipe flow has a closed surface.
What is difference between the open channel and closed channel flow?
open cahannel flow and pipe flow Open channel is always at atmospheric pressure Pipe flow has pressure either above or below atm
What is the relation between alternate depths in rectangular open channels?
In rectangular open channels, alternate depths refer to two different water depths that the flow can take within the channel. These depths are symmetrically positioned about the channel bottom and are a result of the conservation of energy in the flow. The alternate depths occur when the flow transitions between supercritical and subcritical flow conditions within the channel.
What is a control section in open channel flow?
in open channel flow Control sections occur at entrances and exits to channels and at changes in channel slopes, under certain conditions. A gate in a channel can be a control for both the upstream and downstream reaches. In a the flow passes through critical at the entrance to a channel, and the depth can be computed there for a given discharge. The channel is steep; therefore, computations proceed downstream.

Why critical section is a control section in open channel flow?
In open channel flow, the critical section is the point where the flow transitions between subcritical and supercritical states, which significantly affects hydraulic behavior. At this section, the flow velocity and depth reach a critical balance, allowing for the efficient movement of water while minimizing energy losses. The critical depth is essential for analyzing flow characteristics, such as flow rate and energy, and it serves as a control point for determining the behavior of the entire channel system. Understanding the critical section helps engineers design effective drainage systems and manage water resources efficiently.
What is area velocity method?
The area velocity method is a commonly used technique in open channel flow measurement. It involves measuring the velocity of flow at different points in the channel cross-section and integrating these velocities to determine the flow rate. By multiplying the flow rate by the cross-sectional area of the channel, the method can calculate the volume of fluid passing through the channel over time.
What is the difference between internal and external flow?
About of Blood's flow:A fluid flow is classified as being internal or external, depending on whether the fluid is forced to flow in a confined channel or over a surface. The flow of an unbounded fluid over a surface such as a plate, a wire, or a pipe is external flow. The flow in a pipe or duct is internal flow if the fluid is completely bounded by solid surfaces. The flow of liquids in a duct is called open-channel flow if the duct is only partially filled with the liquid and there is an free surface, e.g. the flows of water in rivers and irrigation ditches.

What is Gradually varied flow?
Gradually varied flow refers to a type of open channel flow where the water surface slope changes gradually along the channel length, allowing for a smooth transition between different flow conditions. This occurs when the flow depth varies slowly in space, typically resulting from changes in channel shape or roughness. In such scenarios, the flow remains in a state of equilibrium, governed by forces like gravity, friction, and pressure, and is often analyzed using the principles of gradually varied flow equations in hydraulic engineering. This concept contrasts with rapidly varied flow, where significant changes in flow conditions occur over a short distance.

What is the hydraulic depth?
Hydraulic depth is a measure of the distance from the free surface to the channel bed in a fluid flow system. It is calculated as the cross-sectional area of flow divided by the top width of the flow. It is used in fluid mechanics to analyze the characteristics of open channel flow.
