Axial flow pumps move fluid parallel to the pump shaft.
Jet pumps use a combination of pressure and suction to move fluid.
Other types of pumps include gea
The least count of vernier caliper is the smallest measurement that can be read on the scale.
The least count is determined by the number of divisions on the vernier scale and the main scale.
It is usually 0.1 mm or 0.02 mm for metric vernier calipers and 0.001 inch for imperial vernier calipers.
To determine the least count, subtract the value of one main scale division from the value of one vernier scale division.
For ex...

Herbicide is a type of pesticide used to kill unwanted plants.
Herbicides are chemicals that are used to control or kill unwanted plants.
They are commonly used in agriculture to prevent weeds from competing with crops.
Some herbicides are selective, meaning they only target specific types of plants, while others are non-selective and will kill any plant they come into contact with.
Examples of herbicides include glyphosat...

Bernoulli's theorem explains the relationship between fluid speed and pressure.
Bernoulli's theorem states that as the speed of a fluid increases, its pressure decreases.
It is important in industries such as aviation, where it is used to design wings and airfoils.
It is also used in the design of pipelines and pumps.
Limitations include the assumption of incompressible and non-viscous fluids, and the neglect of friction a...
Pump is used to transfer fluids from one place to another while compressor is used to compress gases.
Pump is used to move fluids like water, oil, etc. from one place to another.
Compressor is used to compress gases like air, refrigerant, etc.
Pumps are used in industries, households, and agriculture while compressors are used in refrigeration, air conditioning, and gas pipelines.
Pumps have a lower pressure ratio while co...
Closing a shutoff valve while the pump is running dry can cause damage to the pump and other components.
The pump will continue to run but without any fluid to circulate, causing it to overheat and potentially seize.
The lack of fluid can also cause damage to the impeller and other internal components.
The pressure in the system can also increase, leading to potential leaks or bursts in the pipeline.
It is important to ens...
Closing the shutoff valve while pumping in a centrifugal pump can cause damage to the pump and the piping system.
The pump will continue to generate pressure, leading to a buildup of pressure in the piping system.
This can cause the pump to overheat and potentially damage the impeller.
The piping system may also experience damage due to the increased pressure.
It is important to ensure that the shutoff valve is only closed...

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.
