6/11 meter radius machine refers to the distance at which a person with normal vision can read letters on a chart.

• 6/11 meter radius machine is used to measure visual acuity.

• It is a standard distance used for eye exams in many countries.

• The machine displays letters of different sizes and the patient is asked to read them from a distance of 6 meters.

• If the patient can read the letters from 6 meters away, they have normal vision.

• If they can only read the letters from a closer di...read more

Electric magnetic stirring system is a method of stirring molten metal using electromagnetic fields.

• It uses a magnetic field to create a rotating motion in the molten metal.

• The system consists of a coil that generates the magnetic field and a power supply to control the frequency and intensity of the field.

• It is commonly used in the steel industry to improve the quality and consistency of the metal.

• It can also be used in the production of aluminum, copper, and other metals.

• Th...read more

Superheat in molten metal is the temperature difference between the actual temperature of the metal and its melting point.

• Superheat is the amount of heat added to the metal above its melting point.

• It is important to maintain the correct superheat to ensure proper casting and solidification.

• Superheat can be measured using thermocouples or pyrometers.

• Excessive superheat can lead to metal shrinkage and porosity, while insufficient superheat can cause incomplete filling of the mo...read more

Technical questions related to thermodynamics and engineering principles.

• Carnot cycle is a theoretical thermodynamic cycle that is the most efficient possible engine cycle.

• Rankine cycle is a thermodynamic cycle used in power plants to convert heat into work.

• A fin is a surface that extends from an object to increase heat transfer.

• Family questions are not related to the job position and should be answered politely.

The melting point of iron is approximately 1,538 degrees Celsius.

• The melting point of iron is an important property in metallurgy.

• Iron transitions from a solid to a liquid state at its melting point.

• The melting point of iron is higher than that of many other common metals.

• Iron's melting point allows it to be easily shaped and molded in various industrial processes.

Negative strip percentage refers to the percentage of defective products in a manufacturing process.

• It is a measure of the quality of the manufacturing process.

• It is calculated by dividing the number of defective products by the total number of products produced and multiplying by 100.

• For example, if a company produces 1000 products and 50 of them are defective, the negative strip percentage would be 5%.

• A high negative strip percentage indicates a need for process improvement...read more

• Make a list of all the appliances in your home and their respective wattages

• Determine the average number of hours each appliance is used per day

• Multiply the wattage of each appliance by the number of hours it is used to get the daily consumption for that appliance

• Add up the daily consumption for all appliances to get the total per day ...read more

There are 4 main types of coal: bituminous, anthracite, peat, and lignite.

• Bituminous coal is the most common type and is used for electricity generation and steel production.

• Anthracite coal is the highest quality coal and has a high carbon content.

• Peat is considered the precursor to coal and is formed from partially decayed plant material.

• Lignite is the lowest quality coal and has a high moisture content.

To connect a single phase motor, you need to identify the terminals, connect the power supply, and ensure proper grounding.

• Identify the terminals on the motor - typically labeled as 'T1', 'T2', and 'T3'.

• Connect the power supply wires to the corresponding terminals on the motor.

• Ensure proper grounding by connecting the motor's grounding terminal to a grounding source.

• Use appropriate tools like screwdrivers, wire strippers, and electrical tape for a secure connection.
