An HVAC flow diagram shows the path of air through a heating, ventilation, and air conditioning system.

• The diagram typically includes components such as air handlers, ductwork, filters, and fans.

• It shows the direction of airflow and the location of temperature and humidity sensors.

• The diagram may also include information about the type of HVAC system, such as a split system or a packaged unit.

• The flow diagram is import...read more

A water system flow diagram illustrates the movement of water through various components of a system.

• The diagram typically includes sources of water, such as reservoirs or wells.

• It shows the pathways through which water flows, such as pipes or channels.

• Components like pumps, valves, and filters are depicted to indicate their role in the system.

• The diagram may also include water treatment processes, such as filtration o...read more

RTD sensor stands for Resistance Temperature Detector sensor. It is a type of temperature sensor that operates on the principle of the temperature dependence of electrical resistance of metals.

• RTD sensors are commonly used in industrial applications for temperature measurement due to their high accuracy and stability.

• They are often made of platinum, nickel, or copper and have a linear relationship between resistance an...read more

Flow meters are devices used to measure the flow rate of a fluid in a pipe or channel.

• Differential pressure flow meters (e.g. Orifice plate, Venturi tube)

• Velocity flow meters (e.g. Turbine, Electromagnetic)

• Positive displacement flow meters (e.g. Piston, Gear)

• Mass flow meters (e.g. Coriolis, Thermal)

Types of reactors include batch reactors, continuous stirred-tank reactors, and plug flow reactors.

• Batch reactors operate in a closed system with a fixed amount of reactants.

• Continuous stirred-tank reactors have continuous flow of reactants and products.

• Plug flow reactors have a continuous flow with no mixing of reactants along the length of the reactor.

Distillation is a process used to separate components of a liquid mixture based on their boiling points.

• Heat is applied to the mixture, causing the component with the lowest boiling point to vaporize first.

• The vapor is then cooled and condensed back into liquid form, resulting in separate fractions.

• This process is commonly used in the production of alcoholic beverages, petroleum refining, and water purification.
