Q1. What is coupling
Ans. 
Coupling is the degree of interdependence between modules in a system.
• Coupling refers to how much one module relies on another module.

• There are different types of coupling such as tight coupling and loose coupling.

• Tight coupling means modules are highly dependent on each other, while loose coupling means they are more independent.

• Reducing coupling in a system can improve its flexibility and maintainability.

• Examples of ...read more

Q3. How many types of reducer
Ans. 
There are two main types of reducers: concentric reducers and eccentric reducers.
• Concentric reducers have a common center line while eccentric reducers have offset center lines.

• Concentric reducers are used when there is a need to maintain the same center line for fluid flow.

• Eccentric reducers are used when there is a need to prevent air or vapor accumulation in the system.

• Examples include reducing from a 6-inch pipe to...read more
