Batch distillation is a process of separating components of a mixture based on their boiling points.
It involves heating a mixture in a batch still and collecting the vapor as it condenses.
The components with lower boiling points will vaporize first and can be collected separately.
The process is repeated multiple times to achieve higher purity of the desired component.
It is commonly used in the production of alcoholic b...

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...

Heat of formation is the energy released or absorbed when one mole of a compound is formed from its elements in their standard states.
Heat of formation is also known as standard enthalpy of formation.
It is typically measured in units of kJ/mol.
Negative heat of formation indicates exothermic reaction, while positive heat of formation indicates endothermic reaction.
For example, the heat of formation of water (H2O) is -28
Heat of reaction is the amount of heat released or absorbed during a chemical reaction.
Heat of reaction can be exothermic (heat released) or endothermic (heat absorbed).
It is typically measured in units of joules or calories.
Examples include combustion reactions releasing heat and photosynthesis reactions absorbing heat.
