Kilometer per hour

Time. Although the SI unit of time is the second, the minute, hour, day, and other calendar units may be necessary where time relates to calendar cycles. Automobile velocity is, for example, expressed in kilometers per hour. 

Aluminum-jacketed calcium silicate insulation with an emissivity factor of 0.05. To convert inches to milhmeters, multiply hy 25.4 to convert miles per hour to kilometers per hour, multiply hy 1.609 and to convert dollars per 1 milhon British thermal units to dollars per 1 million kilojoules, multiply hy 0.948 = 5/9 ( F — 32). 

A US Airways flight leaves Philadelphia in the early evening and arrives in Frankfurt 8.05 hours later. The airline distance from Philadelphia to Frankfurt is about 6.6 X 103 km, depending to some extent on the flight path followed. What is the average speed of the plane, in kilometers per hour ... 

Self-Test A.2B Express an acceleration of 9.81 m-s 2 in kilometers per hour squared. 

Surveying a 10-meter-wide path at 2 kilometers per hour gave 5 pairs of simultaneous samples in filters we could check 400 filters a day with a team of MEDDS dogs. All samples were taken double. The MRV20 sampling vehicle worked 10 hours a day, thus doing 20 kilometers, and 200 samples in the 10 hours. Doing the test directly in the vehicle while on the move would require an analysis every 3 minutes. Each filter would then represent 400 meters times 10 meters. 

Alternatively for an instrument to fit into our process, a third different approach can be used Redo the long positive section with filters but now use much smaller areas to narrow down the position of mines, for example, sections of 10 meters long by 10 meters wide. If the answer would come directly through an analyses of the previous section while one is now sampling the next section, then the process would be continuous. The problem with this third approach was that the changing of the filters between sections becomes a real time-limiting step. Doing 10 meters at 2 kilometers per hour would require a test answer every 18 seconds. 

Survey the road or strip at 2 kilometers per hour in 400-meter lengths, 10 meters wide (3 minutes per strip). 

Wave you ever been asked for your height in centimeters, your weight in kilograms, or the speed limit in kilometers per hour These measurements may seem a bit odd to those folks who are used to feet, pounds, and miles per hour, but the truth is that scientists sneer at feet, pounds, and miles. Because scientists around the globe constantly communicate numbers to each other, they prefer a highly systematic, standardized system. The International System of Units, abbreviated SI from the French term Systeme International, is the unit system of choice in the scientific community. 

A depth gauge uses a unit of length such as feet or meters a speed gauge uses a unit of velocity such as miles per hour (mph) or kilometers per hour (kph) the RPM gauge measures revolutions per minute. 

The more eflicienl defoaming mechanism of spreading involves transpon of underlying liquid so that the liquid is replaced by a film of deloumcr that docs not support foam. A drop of oleic add added to water spreads at a velocity of 30 miles (48.2 kilometers) per hour. The mechanical shock to a film by such a defoamer may be considerable. In addition lo the foam-destroying aspect, spreading is also of value as a defoamer-dispersion method, particularly in viscous or poorly stirred systems. 

Gas pressures in long-distance ptpelines may range from 500 to 5,000 pounds per square inch (34 to 340 atmospheres) with 1,000 psi (68 atmospheres) being quite common Pressure is boosted to make up for frictional losses by use of compressor slalions located every 50 lo 100 miles (80 to 161 kilometers) along the pipeline. In terms of lineal velocity, natural gas may travel at a rate of about 15 miles (24 kilometers) per hour thus, about three days are required lo move a molecule of gas over a distance of 1,000 miles (1609 kilometers). 

The known information is the speed in kilometers per hour the unknown is the speed in miles per hour. Find the appropriate conversion factor, and use the dimensional-analysis method to set up an equation so the km units cancel. 

The reaction happens at lightning speed, with the nitrogen gas filling the air bag at 150 to 250 miles per hour (240 to 400 kilometers per hour). In only about 40 milliseconds, the bag is totally full. 

An Olympic-class sprinter can run 100 meters in about 10.0 seconds. Express this speed in (a) kilometers per hour and (b) miles per hour. 

Convert 55 miles per hour to kilometers per hour. How many kilometers/second is 55 miles per hour (1 mile = 1.6 km)... 

Hydrogen-powered bicycles can go as fast as 15 miles (24 kilometers) per hour.

Velocity is defined to be the rate at which the displacement of an object is changing as time changes. The basic unit of velocity, as of speed, is meters per second. Another common unit is kilometers per hour. If an object is traveling at a constant speed of v meters/second for t seconds and covers d meters, then the formulas connecting these quantities are...
