Maintenance Fundamentals
Importance of Maintenance
Maintenance is the activity of keeping machines, equipment, and systems in proper working condition so that they perform efficiently and safely throughout their service life.
Key Benefits of Maintenance
Increases Equipment Life – Regular maintenance reduces wear and tear.
Improves Reliability – Machines work smoothly with fewer breakdowns.
Ensures Safety – Prevents accidents due to machine failure.
Reduces Breakdown Cost – Early detection avoids
Physics Lab Experiments: Electricity and Magnetism
Activity: Magnetic Field Near Current-Carrying Conductor
To observe the deflection of a magnetic needle placed near a conductor carrying current.
Apparatus and Materials:
Magnetic needle, battery, ammeter, rheostat, key, conducting wire, etc.
Theory:
When electric current passes through a conductor, a magnetic field is produced around it.
Procedure:
- Remove magnetic substances from the table and place the magnetic needle on it. Connect the cell, rheostat, key, and ammeter in series with the experimental
Industrial Filtration Equipment: Types and Operation
1. Plate and Frame Filter
Definition
A plate and frame filter is a pressure filtration equipment used to separate solids from liquids by passing the slurry through filter cloths placed between plates and frames.
Construction
It consists of alternate plates and frames made of cast iron or stainless steel. Each plate is covered with a filter cloth. The frames provide space for solid (cake) collection. The whole assembly is held tightly in a press with inlet and outlet connections.
Working
The slurry is

Distillation Principles and Processes
Distillation is a process by which a liquid mixture is separated into fractions with higher concentrations of certain components by exploiting differences in relative volatility. Distillation is a separation process used to separate components of a liquid mixture based on differences in their boiling points. The process involves heating the mixture to vaporize the most volatile component(s), followed by cooling the vapor to condense it back into liquid form,
