While the first sound moves in superfluid helium at 250 meters per second
, the second sound has a speed of 25 meters per second
'Manila Water continues to implement these interruptions to equitably distribute the limited supply to all of its customers as NWRB has maintained daily raw water allocation at 36 cubic meters per second
despite the improving level of Angat Dam,' Manila Water said in an advisory.
All coastal areas issued a high seas watch on Friday, as winds reached 16 meters per second
and waves as high as four meters.
Referring to the input and output of other dams in the province, Lashkari said that the water input to the Dez dam is currently 1,511 cubic meters per second
and the water output from the dam is 2,000 cubic meters per second
"Our aim for the new e-mobility seals was, therefore, to increase operating rotational speed to at least 40 meters per second
. We achieved this for HS40, and an outstanding 60 meters per second
with PDR RT."
She added that overflow at Kiambere Dam, the last station in the cascade, had subsided to 115.9 cubic meters per second

Chan-Hom may make landfall in Fujian and Zhejiang provinces late on Friday, bringing gales of up to 60 meters per second
Water consumption at this year amounted to 267 cubic meters per second
, last year it was 478 cubic meters per second
Most of the imported wind turbines are designed at high wind speed ratings at 10-13 meter per second, and therefore do not operate properly in Pakistan, where we have average wind speeds in the range of 5-7 meters per second
. This is to be realized that the power in the wind depends upon the cube of the wind speed, hence power in the 8 meter per second wind is only half as compared to the power in the 10 meter per second wind.
Before the improved flow, NamPower last week said the water flow in the Kunene river was at 60 cubic meters per second
, lower than the 70 cubic meters per second
required to operate one turbine and the 280 cubic meters per second

The Vltava River currently flows through Prague at the volume of 3,000 cubic meters of water per second, while the norm is 149 cubic meters per second
and safety barriers along the river were designed to the maximum volume of 3,250 cubic meters per second
