CSTR and PFR are types of reactors, pumps are used to move fluids, heat exchangers transfer heat between fluids.
CSTR (Continuous Stirred Tank Reactor) has a constant volume and operates under steady-state conditions.
PFR (Plug Flow Reactor) has a varying volume and operates under unsteady-state conditions.
Pumps are mechanical devices used to move fluids from one place to another, like centrifugal pumps or positive displ...
Cracking is a process in which complex hydrocarbon molecules are broken down into simpler molecules.
Cracking is a refining process used to convert large hydrocarbon molecules into smaller, more valuable ones.
It is done by breaking the carbon-carbon bonds in the molecules.
Examples include catalytic cracking and steam cracking.
Reforming is a process used in the petroleum industry to convert low-octane naphtha into high-octane gasoline.
Reforming involves rearranging the molecular structure of hydrocarbons to increase their octane rating.
It is typically done using a catalyst at high temperatures and pressures.
The process can also produce hydrogen gas as a byproduct.
Reforming is an important step in the production of gasoline and other fuels in...
The range of a cooling tower refers to the maximum distance at which it can effectively cool air, while the approach is the temperature difference between the cooled water and the entering air.
Range of a cooling tower is typically around 5-20 degrees Fahrenheit
Approach of a cooling tower is usually around 8-15 degrees Fahrenheit
The range and approach of a cooling tower can vary based on factors such as design, size, an

A centrifugal pump is a mechanical device used to transport fluids by converting rotational kinetic energy to hydrodynamic energy.
Centrifugal pumps are commonly used in industries such as oil and gas, chemical, and water treatment.
They work by using an impeller to create a low-pressure area at the center of the pump, which draws in fluid and then expels it at high pressure through the outlet.
Pumps are used to transport...
NPSH stands for Net Positive Suction Head. It is a measure of the pressure available at the suction side of a pump to prevent cavitation.
NPSH is important in pump selection and operation.
It is the difference between the total suction head and the vapor pressure of the pumped fluid.
Insufficient NPSH can lead to cavitation, which can damage the pump and reduce its efficiency.
Different types of pumps have different NPSH r...

Pressure and velocity compounding are methods used to increase the efficiency of steam turbines.
Pressure compounding involves dividing the pressure drop across the turbine into smaller stages, each with its own set of moving blades.
Velocity compounding involves dividing the steam flow into smaller streams, each flowing through a set of fixed blades.
Both methods increase the efficiency of the turbine by reducing the amo...
Iron-iron carbide diagram is a graphical representation of the phases of iron and carbon at different temperatures and compositions.
Also known as the Fe-C diagram
Shows the transformation of iron from ferrite to austenite to pearlite
Used to determine the microstructure and properties of steel
Helps in designing heat treatment processes for steel
Important tool for metallurgists and materials engineers
Normalizing, annealing, and hardening are heat treatment processes used to alter the properties of metals.
Normalizing involves heating the metal to a temperature above its critical point and then cooling it in air. This process improves the strength and toughness of the metal.
Annealing involves heating the metal to a specific temperature and then cooling it slowly. This process reduces the hardness and increases the du...
Efficiency of Rankine cycle formula.
Efficiency = (Net work output / Heat input)
Efficiency = (1 - T2/T1)
T1 is the temperature of steam at the inlet of turbine
T2 is the temperature of steam at the outlet of turbine
Net work output = (P1 - P2) * (V2 - V1)
Heat input = m * (h1 - h2)
m is the mass flow rate of steam
h1 is the enthalpy of steam at the inlet of turbine
h2 is the enthalpy of steam at the outlet of turbine

Reflux ratio is the ratio of the amount of liquid refluxed to the amount of liquid that is being distilled.
It is an important parameter in distillation processes.
It helps in determining the efficiency of the distillation column.
A high reflux ratio results in a higher purity of the distillate.
Reflux ratio can be adjusted to optimize the distillation process.
It is calculated as the ratio of the reflux flow rate to the di

Modes of heat transfer include 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, such as air or water.
Radiation is the transfer of heat through electromagnetic waves, such as the heat from the sun.
Examples of conduction include touching a hot stove or holding a cold dr...
Design of distillation column involves determining the number of trays, column diameter, and feed location.
The number of trays is determined by the separation required and the reflux ratio.
Column diameter is determined by the vapor and liquid flow rates.
Feed location is determined by the composition of the feed and the desired product purity.
Other factors to consider include pressure drop, heat transfer, and material s...
