Calorific value is the amount of heat energy released when a unit mass of fuel is burned.

• Calorific value is measured in units of energy per unit of mass.

• It is used to compare the energy content of different fuels.

• Higher calorific value means more energy is released per unit mass of fuel.

• Examples of fuels with high calorific value include coal, natural gas, and diesel.

• Calorific value can be affected by factors such as moisture content and impurities in the fuel.

Yes, there is a policy for manual scavengers.

• The Prohibition of Employment as Manual Scavengers and their Rehabilitation Act, 2013 prohibits manual scavenging and provides for rehabilitation of manual scavengers.

• The act also provides for the identification, survey, and rehabilitation of manual scavengers.

• The government has launched various schemes for the rehabilitation of manual scavengers, such as the Self Employment Scheme for Rehabilitation of Manual Scavengers (SRMS) and...read more

To swap two numbers without using a third variable, use arithmetic operations.

• Assign the sum of the two numbers to the first number

• Subtract the second number from the sum and assign it to the second number

• Subtract the original first number (now stored in the second number) from the sum and assign it to the first number

Ash is the residue left after the combustion of organic materials.

• Ash is the inorganic material that remains after the complete combustion of organic substances.

• It is typically composed of minerals, metals, and other non-combustible elements.

• Examples of ash include the residue left after burning wood, coal, or paper.

• Ash can vary in color and composition depending on the source material.

• It is commonly used as a fertilizer, in construction materials, or in the production of cer...read more

WHRB in rotary kiln stands for Waste Heat Recovery Boiler, which is used to recover heat from the exhaust gases of the kiln.

• WHRB is a type of boiler that captures and reuses the heat energy from the exhaust gases of a rotary kiln.

• It helps in improving the overall energy efficiency of the kiln operation.

• The recovered heat can be used for various purposes such as preheating combustion air or generating steam for power generation.

• WHRB systems are commonly used in industries like...read more

Yes, ISO 9000 is a set of international standards for quality management and quality assurance.

• ISO 9000 is a series of standards developed by the International Organization for Standardization (ISO) that focus on quality management systems.

• These standards provide guidance and tools for companies to ensure their products and services consistently meet customer requirements and regulatory standards.

Manual scavenging is the practice of manually cleaning, carrying, disposing or handling in any manner, human excreta.

• Manual scavenging is a caste-based occupation in India

• It is a violation of human rights and is illegal in India

• It is a dangerous and degrading practice that exposes workers to diseases and health hazards

• It is often done without proper protective gear or equipment

• Examples include cleaning of dry latrines, septic tanks, and open drains

Ash has various uses in different industries and applications.

• Ash is commonly used in construction as a substitute for cement in concrete production.

• It is also used in the manufacturing of bricks, ceramics, and glass.

• In agriculture, ash can be used as a fertilizer due to its high mineral content.

• Ash is used in the production of soap and detergents.

• It is utilized in the production of certain metals, such as aluminum and zinc.

• Ash can be used as a raw material in the production ...read more

Iron smelting process is a method of extracting iron from its ore using heat and reducing agents.

• Iron ore is heated in a blast furnace with coke (carbon) and limestone as reducing agents.

• The coke burns to produce carbon monoxide, which reacts with the iron ore to release the iron metal.

• The limestone helps to remove impurities from the iron ore, forming slag as a byproduct.

• The molten iron is then collected at the bottom of the furnace and cast into molds to form ingots or othe...read more

Sponge iron is a metallic product produced through the direct reduction of iron ore in the form of lumps, pellets, or fines.

• Sponge iron is also known as direct reduced iron (DRI).

• It is produced by removing oxygen from iron ore through a chemical reaction using natural gas or coal as a reducing agent.

• Sponge iron is used as a raw material in the production of steel through the electric arc furnace (EAF) or basic oxygen furnace (BOF) processes.

Fe-C diagram shows phases of iron-carbon system at different temperatures and compositions.

• Fe-C diagram is a graphical representation of the phases of iron-carbon system.

• It shows the phases present at different temperatures and compositions.

• Examples of phases include austenite, ferrite, cementite, and pearlite.

MCB, or Miniature Circuit Breaker, protects electrical circuits from overloads and short circuits by automatically switching off.

• MCB detects overloads and interrupts the circuit to prevent damage.

• It resets automatically after the fault is cleared, unlike fuses.

• Commonly used in residential and commercial electrical systems.

• Example: An MCB will trip if too many appliances are connected to a single circuit.
