Exhaust CFM can be calculated by determining the air volume flow rate in cubic feet per minute.

• Determine the area of the exhaust opening

• Measure the velocity of the air being exhausted

• Multiply the area by the velocity to get the air volume flow rate in cubic feet per minute

Treated fresh unit equipment parts are components used in the treatment of fresh water in a unit.

• Pumps

• Filters

• Valves

• Chemical dosing systems

• Control panels

• Flow meters

Duct size can be calculated based on the required airflow, velocity, and friction loss.

• Determine the required airflow for the space or system.

• Calculate the velocity of the air based on the desired airflow and the cross-sectional area of the duct.

• Consider the friction loss in the duct system due to fittings, bends, and length.

• Use duct sizing charts or software to find the appropriate duct size based on the calculated velocity and friction loss.

• Ensure the selected duct size mee...read more

AHU and chiller are essential components of HVAC systems.

• AHU stands for Air Handling Unit and is responsible for circulating and conditioning air within a building.

• Chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle.

• AHU and chiller work together to provide cooled air to the building.

• AHU takes in outside air, filters it, cools or heats it, and then distributes it through ductwork.

• Chiller cools the water or refrigerant ...read more

The current CTC and expected CTC are financial aspects of the job that need to be discussed during the negotiation process.

• Current CTC refers to the current salary or compensation package of the candidate.

• Expected CTC refers to the salary or compensation package the candidate is looking for in the new role.

• These figures are important for both the employer and the candidate to ensure alignment and avoid any misunderstandings.

• It is common for candidates to expect a higher CTC w...read more

Ventilation CFM is calculated by determining the volume of air to be exchanged per minute.

• CFM stands for Cubic Feet per Minute.

• To calculate ventilation CFM, you need to know the volume of the space and the desired air exchange rate.

• The formula to calculate CFM is: CFM = (Volume of Space) x (Air Exchange Rate)

• For example, if the volume of a room is 1000 cubic feet and the desired air exchange rate is 5 times per hour, the CFM would be 5000 (1000 x 5).

TFA stands for Thin Film Antenna. It is a type of antenna that uses a thin film of conductive material to transmit and receive signals.

• TFA works on the principle of using a thin film of conductive material as the antenna element.

• The conductive film is usually made of materials like copper or gold.

• The film is deposited on a substrate, which provides mechanical support and insulation.

• TFA antennas are lightweight, flexible, and can be easily integrated into various devices.

• They ...read more

Duct size is determined by the gauge of the material used.

• Duct size refers to the dimensions of the ductwork used in HVAC systems.

• The gauge of the material refers to its thickness or weight.

• Thicker gauge materials are used for larger duct sizes to ensure structural integrity.

• Common gauges for ductwork range from 26 to 16, with lower numbers indicating thicker materials.

• For example, a 16-gauge duct would be used for larger duct sizes, while a 26-gauge duct would be used for sm...read more

The number of pole 1km cabling required depends on the specific project requirements and design considerations.

• The number of pole 1km cabling needed will depend on the distance to be covered and the spacing between poles.

• Factors such as terrain, existing infrastructure, and local regulations will also impact the number of poles required.

• For example, in a straight road with no obstacles, fewer poles may be needed compared to a winding road with obstacles.

• Consulting with a stru...read more

The size of the pole base plate depends on the load requirements and soil conditions.

• The size of the pole base plate should be determined by the structural engineer based on the load requirements of the pole.

• The soil conditions at the site also play a crucial role in determining the size of the base plate.

• Factors such as wind load, seismic activity, and the weight of the pole itself should be considered when determining the size of the base plate.
