Uniformity factor is the ratio of the minimum illuminance to the average illuminance on a surface. Maintenance factor is the ratio of the illuminance after a period of time to the initial illuminance.

• Uniformity factor is important in lighting design to ensure consistent lighting levels across a space.

• A higher uniformity factor indicates more even lighting distribution.

• Maintenance factor accounts for factors like dirt a...read more

To conduct a slump test, fill a metal cone with concrete, compact it, remove the cone, and measure the slump.

• Clean the cone and moisten it with water.

• Fill the cone with concrete in three layers, compacting each layer with a rod.

• Remove the cone and place it next to the slump.

• Measure the difference in height between the top of the cone and the highest point of the slump.

• Repeat the test at least twice and take the average

Delta start is a method of starting three-phase induction motors.

• Delta start involves connecting the motor windings in a delta configuration during starting.

• This reduces the voltage applied to each winding, limiting the starting current.

• Once the motor reaches a certain speed, the windings are switched to a star configuration for normal operation.

• Delta start is commonly used for motors with high starting currents, such
