Supply Chain Interview Questions and Answers for Freshers

PID control system is used to regulate flow rate and temperature of milk in the factory.

• PID control system stands for Proportional-Integral-Derivative control system.

• It continuously monitors and adjusts the flow rate and temperature of milk.

• Proportional control component adjusts the control output based on the error between desired and actual values.

• Integral control component eliminates steady-state errors by integrating the error over time.

• Derivative control component predic...read more

Bearing material is chosen based on factors like load capacity, speed, lubrication, and environmental conditions.

• Bearing materials should have high strength and hardness to withstand heavy loads.

• Materials like steel, bronze, and ceramic are commonly used for bearings.

• Steel bearings are suitable for high-speed applications and can handle heavy loads.

• Bronze bearings are self-lubricating and resistant to corrosion.

• Ceramic bearings offer high temperature resistance and are lightw...read more

A pressure cooker works by trapping steam inside a sealed pot, which raises the temperature and pressure, cooking food faster.

• Pressure cookers have a sealed lid that locks in place

• Water or other liquid is added to the pot to create steam

• The steam raises the temperature and pressure inside the pot, cooking food faster

• Pressure cookers are great for cooking tough cuts of meat or beans quickly

• They can also be used for canning fruits and vegetables

SI and CI engines are different types of internal combustion engines.

• SI stands for Spark Ignition and CI stands for Compression Ignition.

• SI engines use a spark plug to ignite the fuel-air mixture, while CI engines rely on compression to ignite the fuel.

• SI engines are commonly used in gasoline-powered vehicles, while CI engines are used in diesel-powered vehicles.

• SI engines generally have higher power output and better acceleration, while CI engines have better fuel efficiency...read more
