The principle of a pump is to create flow and increase pressure of a fluid by converting mechanical energy into hydraulic energy.

• Pumps work by using an impeller or rotor to create a centrifugal force that pushes the fluid through the pump.

• The pump increases the pressure of the fluid by adding energy to the system.

• There are different types of pumps such as centrifugal pumps, positive displacement pumps, and diaphragm pumps.

• Examples of pumps include water pumps, fuel pumps, and...read more

Petrol and diesel have different densities.

• Petrol has a lower density than diesel.

• The density of petrol is around 0.71 to 0.77 grams per cubic centimeter.

• The density of diesel is around 0.82 to 0.85 grams per cubic centimeter.

• Density is a measure of mass per unit volume.

A pump is a mechanical device used to move fluids from one place to another.

• Pumps are used in various industries such as agriculture, construction, and manufacturing.

The machine starts automatically in robot mode when a part is detected.

• The machine is equipped with sensors to detect the presence of a part

• Once a part is detected, the machine switches to robot auto mode for operation

• This automation helps in efficient and accurate processing of parts

Centrifugal pumps are named so because they use centrifugal force to generate pressure and move fluid.

• Centrifugal pumps work by converting rotational kinetic energy into hydrodynamic energy.

• The pump's impeller spins rapidly, creating a centrifugal force that pushes the fluid towards the outer edges of the impeller.

• This centrifugal force increases the fluid's velocity and pressure, allowing it to be discharged through the pump's outlet.

• Centrifugal pumps are commonly used in va...read more

Work is the effort put into achieving a goal while maintenance is the act of preserving or restoring something.

• Work involves performing tasks to achieve a specific objective or goal.

• Maintenance involves keeping something in good condition or restoring it to its original state.

• Work is usually a temporary activity while maintenance is ongoing.

• Examples of work include building a structure, repairing a machine, or completing a project.

• Examples of maintenance include cleaning, rep...read more

Cleaning an injection moulding part involves removing any residue or contaminants to ensure quality production.

• Use appropriate cleaning solutions and tools to remove any residue from the moulded part.
