To calculate the amount of ballast needed for a hole measuring 10 feet by 10 feet by 4 feet, first find the volume of the hole by multiplying the dimensions: 10 x 10 x 4 = 400 cubic feet. The amount of ballast required will depend on the type of ballast and its density, but if you need to fill the hole completely, you would need 400 cubic feet of ballast. Make sure to consider any compaction or settling that may occur when choosing the amount to use.
Electronic ballast does not hum as much as a choke. Minute hum of electronic ballast is the small inductor and capacitor producing an oscillation for high voltage generation,
A jumbo bag of ballast typically contains around 1 ton or 2000 pounds of material. This is equivalent to approximately 0.9 cubic meters or 31.5 cubic feet of ballast.
The cost to replace a fluorescent ballast typically ranges from $50 to $100, including the cost of the ballast itself and labor for installation. It's recommended to hire a professional electrician to ensure the job is done safely and correctly.
The cost of a ballast tank can vary depending on the size, material, and specific requirements. Generally, smaller ballast tanks for recreational boats can range from a few hundred to a few thousand dollars, while larger industrial tanks can cost tens of thousands or more.
A fluorescent fixture with no tubes installed will still consume power, typically around 5-10 watts due to the ballast and other internal components. This power consumption is significantly lower compared to when the tubes are installed and the fixture is operating normally.
None it's a hole
The ballast is determined by how many passengers are present on each trip and the amount of lift that the balloon provides at takeoff. So if there's a lot of people onboard less ballast is needed and vice versa. In general it's less than 300lbs.

A 4x4x4 foot hole requires 64 cubic feet of concrete or .8 (8 tenths) of a yard.
(3 x 2 x depth of the hole in feet) cubic feet
A jumbo bag of ballast typically contains around 1 ton or 2000 pounds of material. This is equivalent to approximately 0.9 cubic meters or 31.5 cubic feet of ballast.
The amount of cement to add to one ton of ballast depends on the desired concrete mix ratio. A common mix ratio for general-purpose concrete is 1 part cement to 4 parts ballast, which would mean adding approximately 0.25 tons (or 250 kg) of cement to one ton of ballast. However, specific project requirements may necessitate adjustments to this ratio. Always consult relevant guidelines or specifications for the exact mix needed.
The amount of ballast used in a bottle rocket typically depends on the size of the bottle and the desired flight characteristics. A good starting point is to use around 10-20% of the bottle's total weight in ballast. It's important to experiment, as too much ballast can hinder flight, while too little may result in instability. Adjust the ballast based on test flights to achieve optimal performance.
1 cubic yard of railroad ballast typically weighs between 2,000 to 2,700 pounds.
These tubes need a ballast to operate the tubes. The current and voltage will be marked on the fixtures ballast.
