New technology in LNG tank construction

The welding procedure was developed to allow arc blow to occur. A longer arc length than typical was applied which results in a higher voltage. Using a longer arc length does result in more spatter during the test, but increases the sensitivity to arc blow. This worst case scenario provided appropriate circumstances to test the effectiveness of ...

Wind Turbine Speed TurbineGenerator

Wind Turbine Speed TurbineGenerator

Wind Turbine Tip Speed Ratio (TSR) is the speed of the tip divided by the speed of the wind. For example if the tip speed is 120 miles/hour and the wind speed is 20 miles/hour than the TSR = 120 / 20 = 6. The optimum tip TSR depends on how many blades are used to operate the wind turbine: 2 Blades : optimum ratio is around 6
