2. Duct (flow) - Wikipedia

   en.wikipedia.org/wiki/Duct_(flow)

   Ducts for air pollution control in a 17000 standard cubic feet per minute regenerative thermal oxidizer (RTO). A round galvanized steel duct connecting to a typical diffuser Fire-resistance rated mechanical shaft with HVAC sheet metal ducting and copper piping, as well as "HOW" (Head-Of-Wall) joint between top of concrete block wall and underside of concrete slab, firestopped with ceramic ...

3. Pipe flow - Wikipedia

   en.wikipedia.org/wiki/Pipe_flow

   In fluid mechanics, pipe flow is a type of fluid flow within a closed conduit, such as a pipe, duct or tube. It is also called as Internal flow. [1] The other type of flow within a conduit is open channel flow. These two types of flow are similar in many ways, but differ in one important aspect.

4. Damper (flow) - Wikipedia

   en.wikipedia.org/wiki/Damper_(flow)

   This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...

5. Friction loss - Wikipedia

   en.wikipedia.org/wiki/Friction_loss

   Note in passing that selecting a duct with diameter D = 0.6 m (24 in.) will result in a loss Δp / L of 0.02 kg / m 2 / s 2 (0.02 in H 2 O per 100 ft), illustrating the great gains in blower efficiency to be achieved by using modestly larger ducts. The following table gives flow rate Q such that friction loss per unit length Δp / L (SI kg / m ...

6. Control chart - Wikipedia

   en.wikipedia.org/wiki/Control_chart

   Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.

7. Fanno flow - Wikipedia

   en.wikipedia.org/wiki/Fanno_flow

   The viscous friction causes the flow properties to change along the duct. The frictional effect is modeled as a shear stress at the wall acting on the fluid with uniform properties over any cross section of the duct. For a flow with an upstream Mach number greater than 1.0 in a sufficiently long duct, deceleration occurs and the flow can become ...

8. Diffuser (thermodynamics) - Wikipedia

   en.wikipedia.org/wiki/Diffuser_(thermodynamics)

   Ducts containing fluids flowing at low velocity can usually be analyzed using Bernoulli's principle. Analyzing ducts flowing at higher velocities with Mach numbers in excess of 0.3 usually require compressible flow relations. [2] A typical subsonic diffuser is a duct that increases in area in the direction of flow. As the area increases, fluid ...

9. Hard suction hose - Wikipedia

   en.wikipedia.org/wiki/Hard_suction_hose

   Flexible suction hose, also known as a suction hose, is a specific type of rigid fire hose used in drafting operations. When using this technique, the fire engine draws water for fire fighting from an unpressurized supply, such as a portable water tank, pool, or other static water source, instead of drawing water from a pressurized water supply, such as a fire hydrant.
