Scanning a 360-degree revolution per second
for pipelines up to 18 feet in diameter, today's sonar technology enables inspection in both charged and semi-charged conditions by including the option of a mounted CCTV system for simultaneous inspection above and below the waterline, producing the results into one composite view.
Radio observations of J0108 show it to be one of the oldest and faintest pulsars known, spinning only slightly faster than one revolution per second
The unit has scan rates up to 1,000 points per second and rotational speeds up to 1 revolution per second
. With Z-axis resolutions down to 0.125 mm, Theta Star is ideal for checking heights and depths, as well as wall and coating thickness.
On all hand crank models we sell, the handle needs to be cranked at 60 rpm (one revolution per second
Find a length of cord where both ends reach up to your armpits when you stand on it, and start by skipping with both feet together for a couple of minutes at about one revolution per second
. Try to increase the skipping speed - and time spent skipping - gradually until you can reach ten minutes every day without too much discomfort.
For this configuration, a 0.07-lb increase in line tension resulted from every revolution per second
of the spool.
