Ballast is typically a layer of coarse stones used to provide support and stability for railroad tracks or as a base for roads. It is not commonly used as a sub base for construction projects as it lacks the necessary strength and compaction characteristics required for a stable foundation. It's best to use materials specifically designed for sub base applications, such as crushed stone or gravel.
What else can I help you with?
Can you use a 70 watt metal halide lamp in a 150 watt ballast?
No, it is not recommended to use a 70 watt metal halide lamp with a 150 watt ballast. The lamp and ballast wattage should match to ensure proper operation and to prevent damage to the lamp or ballast. It is best to use a compatible lamp and ballast with matching wattages.
What type of a ballast do compact fluorescent lamps use?
Compact fluorescent lamps (CFLs) use electronic ballasts, which regulate the flow of current to the lamp. These ballasts provide benefits such as improved energy efficiency, reduced flicker, and a quieter operation compared to magnetic ballasts.
Can you connect a 240V ballast to 208V line service?
It is not recommended to connect a 240V ballast to a 208V line service as this can potentially damage the ballast and create a safety hazard. It is best to use a ballast that is specifically designed for use with a 208V line service to ensure safe and proper operation.
Can you use a 70 watt high pressure sodium bulb in a 100 watt ballast?
No. The bulb has to match the ballast wattage exactly. And you can't interchange different lamps (like metal halide) either. The ballast is specific to that wattage and lamp type. The bulb will either burn out quickly or just not work properly at all
What size ballast do you use for a 4 foot tube?
When the ballast is to be purchased, look at the schematic that is on the label of the ballast. There it will tell you which ballast is good for which lamps and also let you know what length of tube the ballast is good for. Most of the new electronic ballasts allow for multiple connections of different size lamps.
How does a sub sink?
flood the ballast
How does a submarine change its density?
To be able to submerge in the water, the sub has to become heavier. Ballast tanks are utilzed for this purpose. Water is let into them, and the sub sinks. To rise, air is pumped into the ballast tanks, and the sub rises.
How does a submarine dive and surface?
Massive ballast tanks can be filled with water or air, changing the weight and buoyancy of a sub. Once dived a sub can use hydroplanes to angle it towards the surface and use propulsion to drive to the surface.
What is the purpose of a submarine's ballast tanks?
to keep the sub level or help it to dive and surface
What is the purpose of a submarine's ballast tank?
to keep the sub level or help it to dive and surface
How do you use ballast in a sentence?
The boat had two different types of ballast.
What is the purpose of a submarine ballast tasks?
They help the sub go up and down. When water is allowed into the tanks, the sub goes down. When water is pushed out of the tanks, sub comes up.
Can you use 5300k hid bulbs with 8000k ballast?
A ballast is a ballast in most cases. So yes you should be fine.
Can you use a 70 watt metal halide lamp in a 150 watt ballast?
No, it is not recommended to use a 70 watt metal halide lamp with a 150 watt ballast. The lamp and ballast wattage should match to ensure proper operation and to prevent damage to the lamp or ballast. It is best to use a compatible lamp and ballast with matching wattages.
Does a tube light glow without starter?
yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.
Can you use 250W metal halide bulb in a 1000W metal halide ballast?
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
How does a submarine work?
A submarine has tanks that are called ballast tanks. When these tanks are flooded with sea water, the submarine sinks because the sub weighs more than the water it displaces. To rise again, the sub reduces its weight by pushing compressed air into the ballast tanks. The air forces the sea water out and sub returns to the surface. It maneuvers using its rudder and planes.
