There are several types of reactors, primarily categorized into nuclear and chemical reactors, each serving distinct purposes.

• Nuclear Reactors: Used for generating energy through nuclear fission (e.g., Pressurized Water Reactor).

• Chemical Reactors: Facilitate chemical reactions (e.g., Batch Reactor, Continuous Stirred Tank Reactor).

• Bioreactors: Used for biological processes, such as fermentation (e.g., Fermenter).

• Photor...read more

Centrifuges typically have two to four bearings, depending on the design and size of the machine.

• Bearings support the rotor and allow it to spin smoothly.

• Common types of bearings used include ball bearings and roller bearings.

• The number of bearings can vary based on the centrifuge's capacity and intended use.

• For example, a small laboratory centrifuge may have two bearings, while a large industrial centrifuge may have f...read more

A gearbox transmits power from the engine to the wheels, allowing for speed and torque adjustments in vehicles.

• Gearboxes use gears of different sizes to change the speed and torque of the vehicle.

• In a manual gearbox, the driver selects gears using a clutch and gear stick.

• Automatic gearboxes shift gears automatically based on speed and engine load.

• Example: In a manual car, shifting from 1st to 2nd gear increases speed w...read more

Cooling tower capacity refers to the ability of a cooling tower to dissipate heat from a system efficiently.

• Cooling tower capacity is measured in tons or BTUs per hour.

• Factors affecting capacity include water flow rate, temperature difference, and ambient conditions.

• For example, a cooling tower with a capacity of 100 tons can remove heat equivalent to 120,000 BTUs per hour.

• Proper sizing is crucial; undersized towers ca...read more

An Air Handling Unit (AHU) circulates and conditions air in HVAC systems, ensuring comfort and air quality in buildings.

• AHUs consist of fans, heating/cooling coils, filters, and dampers to manage air flow.

• They can be used for both heating and cooling, depending on the system design.

• Regular maintenance, such as filter changes, is crucial for optimal performance.

• Example: In a commercial building, an AHU might regulate te...read more
