Fire point is the temperature at which a fuel continues to burn after ignition, while flash point is the temperature at which a fuel produces a flammable vapor.
Fire point is higher than flash point.
Flash point is the minimum temperature at which a liquid gives off vapor in sufficient concentration to ignite.
Fire point is the temperature at which a fuel sustains combustion once ignited.
Flash point is used to classify fl...
Flash distillation is a single-stage process where a liquid mixture is vaporized quickly, while fractional distillation is a multi-stage process where the mixture is separated into fractions based on boiling points.
Flash distillation is a rapid vaporization process used for separating components with large differences in boiling points.
Fractional distillation is a slower process that involves multiple distillation stag...
The terms 'flammable' and 'inflammable' mean the same thing - capable of catching fire easily.
Both 'flammable' and 'inflammable' mean easily ignited and capable of catching fire.
The prefix 'in-' in 'inflammable' does not mean 'not' as in other words, but rather intensifies the meaning.
The use of 'inflammable' can sometimes cause confusion due to the misconception that it means 'not flammable'.
Different types of permits related to safety include building permits, fire permits, and health permits.
Building permits are required for construction, renovation, or demolition of buildings to ensure compliance with safety codes.
Fire permits are necessary for activities involving fire hazards, such as fireworks displays or bonfires.
Health permits are needed for businesses that handle food or provide health services to

The theoretical plate height in packed bed and distillation columns is a measure of the efficiency of separation.
The theoretical plate height in packed bed columns is typically calculated using the HETP (Height Equivalent to a Theoretical Plate) equation.
In distillation columns, the theoretical plate height is a measure of the height of an idealized theoretical plate required for a given separation efficiency.
Theoretic...
To dilute a 12% NaOH solution to 5%, calculations involve using the formula C1V1 = C2V2 and determining the amount of water needed.
Use the formula C1V1 = C2V2, where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.
Calculate the volume of the initial 12% NaOH solution needed using the formula V1 = (C2 * V2) / C1.
Subtract the initial volume from the fin...

DG works as a backup power source during power failure.
DG stands for Diesel Generator.
It automatically starts when there is a power failure.
It provides power to essential equipment and systems.
It requires regular maintenance and fuel supply.
Examples of essential systems powered by DG are elevators, emergency lights, and fire alarms.
Chlorine gas (Cl2) can be identified by its pungent odor and yellow-green color.
Use a gas detector to measure the concentration of Cl2 in the air.
Look for signs of respiratory irritation or difficulty breathing in individuals exposed to Cl2.
Check for yellow-green discoloration on surfaces or in the air.
Be aware of potential sources of Cl2, such as swimming pools, water treatment plants, and chemical manufacturing facil

Polar solvents have a positive and negative end, while nonpolar solvents have no charge.
Polar solvents dissolve polar solutes and nonpolar solvents dissolve nonpolar solutes.
Water is a polar solvent, while oil is a nonpolar solvent.
Polarity is determined by the electronegativity difference between atoms in a molecule.
A fire extinguisher is a device used to control or extinguish small fires. There are different classes of fire extinguishers for different types of fires.
Fire extinguishers are classified based on the type of fire they can extinguish.
Class A fire extinguishers are used for fires involving ordinary combustibles like wood, paper, or cloth.
Class B fire extinguishers are used for fires involving flammable liquids like gaso...
Safety valves and rupture discs are important safety devices in production processes.
Safety valves are designed to release excess pressure in a system to prevent explosions or other hazardous situations.
Rupture discs are used as a backup to safety valves and are designed to burst at a predetermined pressure to release excess pressure.
Both safety valves and rupture discs are critical components in ensuring the safety of...
Heat exchanger design involves selecting appropriate materials, determining heat transfer coefficients, and optimizing flow rates.
Consider the type of fluid being used and its properties
Choose materials that can withstand the temperature and pressure of the fluids
Calculate the heat transfer coefficients for each fluid
Optimize the flow rates to maximize heat transfer efficiency
Consider the overall size and cost of the h
Material balance and energy balance equations are used to track the flow of materials and energy in a system.
Material balance equation is based on the principle of conservation of mass.
Energy balance equation is based on the principle of conservation of energy.
Material balance equation: Input = Output + Accumulation
Energy balance equation: Input = Output + Storage + Losses
Example: In a chemical reactor, the material ba...
Heat transfer occurs in three modes: conduction, convection, and radiation.
Conduction is the transfer of heat through a material without any movement of the material itself.
Convection is the transfer of heat through the movement of fluids or gases.
Radiation is the transfer of heat through electromagnetic waves.
Examples of conduction include touching a hot stove or iron, while examples of convection include boiling wate...
Centrifugal force is the apparent force that acts outward on a body moving around a center, arising from the body's inertia.
Centrifugal force is not a real force, but rather a perceived force.
It is the result of an object's inertia trying to keep it moving in a straight line while it is being forced to move in a circular path.
Examples include the feeling of being pushed to the side in a car when turning a corner, or th...
There are various types of dryers used in production, including rotary dryers, fluidized bed dryers, and spray dryers.
Rotary dryers use a rotating drum to dry materials.
Fluidized bed dryers use hot air to suspend and dry materials.
Spray dryers use a nozzle to spray liquid into a hot air stream, creating a fine powder.
Other types of dryers include freeze dryers, vacuum dryers, and paddle dryers.
