MTU Onsite Energy Projects. 1  Oceanic Time Warner Cable Hawaii - Oceanic Time Warner currently uses MTU Onsite energy for its backup power and power generation systems. Currently, Time Warner Cable has about 15 MTU Onsite Energy 50, 250, and 350 kW diesel gen-set and transfer switches for location on Oahu and the Big Island.
The concrete calculator is calibrated to exactly 23.60 kN/m3 unit weight per concrete volume. Which is, as Internationally defined, how heavy is normal reinforced concrete. In USCS units (United States Customary System units), its weight comes to ~150lb/ft3 and ~2,400 kg/m3 if measured in Metric SI system.
The density of concrete varies with its exact composition, but averages around 2,400 kg per cubic meter, or 150lbs per cubic foot. So a cube of concrete 1 foot on each side weighs 150lbs on dry land. We say that this concrete block displaces 1 cubic foot of water. The same volume of sea water weighs 64 pounds, which is the upward buoyant force that is applied to this concrete block when it sits on the bottom of the ocean. The apparent weight of this block will be 86 pounds, which its actual weight of 150lbs (downward force) minus its buoyancy of 64 pounds (upward force).
