Right Answer:
A cascade loop is a control system that uses two controllers: a primary (master) controller and a secondary (slave) controller. The primary controller sets the setpoint for the secondary controller, allowing for more precise control of a process. It is used instead of a single PID loop when the process has a fast dynamic response that needs tighter control, as it can reduce the effect of disturbances and improve stability.

In a cascade loop, the secondary (slave) loop is faster because it responds to changes more quickly, while the primary (master) loop is slower as it manages the overall process setpoint.

Right Answer:
A Reverse Osmosis (R.O.) Plant is a water purification system that uses a semi-permeable membrane to remove impurities, salts, and contaminants from water by applying pressure, allowing only water molecules to pass through while blocking larger molecules and ions.
