Supplement
Here there is an instruction on how this slide this clock works [...]
it is (the images you can only see in the link)
General function of the slide rule
1) multiplication
[Example]
12 x 15
[Setting]
Put the 12 on the outer scale to the 10 on the inner scale. The 15 on the inner scale corresponds to 18 on the outer scale. Hang the decimal position a zero, the result is thus 180. It should be noted that the scale of this clock have no decimal point.
2) Division
[Example]
300/15
[Setting]
Put the 30 of the outside scale to the 15 of the inner scale. The 10 of the inner scale corresponds to 20 on the outer scale. Consider the position of the decimal point to obtain 20 as a result.
3) Reading Ratios
[Example]
50/20 = 30 / x
[Setting]
Put the 50 of the outside scale to the 20 of the inner scale. The 30 on the outer scale corresponds to 12 on the inner scale. The ratio of all internal and external values of the scale are "50:20".
4) determining the square root
[Example]
Square root of 169
[Setting]
Rotate the slide slowly to find a value that corresponds to both 16.9 on the outer scale and the inner scale of 10. In this example, corresponds to 16.9 on the outer scale of the inner scale 13 and 10 of the inner scale corresponds to 13 on the outer scale. Consequently the result. 13
Navigation Calculator for motor sports
1) Time required
[Example]
Obtain the time required at 55 km / h for 330 km.
[Setting]
Put the 55 of the outer scale with the SPEED INDEX (MPH) on the inner scale. Found to comply with the 33 on the outer scale "6:00" on the inner scale (time scale). Consequently, the required time is 6 hours.
* The result can also be calculated in miles rather than in kilometers.
2) Speed
[Example]
What is the speed at a distance of 120 km in a time of 1 hour and 30 minutes?
[Setting]
Put the 12 on the outer scale with "1:30" on the inner scale (time scale). The SPEED INDEX (MPH) on the inner scale corresponds to 80 on the outer scale. Consequently, the speed is 80 km / h
,
3) mileage
[Example]
We are looking for the total number of kilometers at a speed of 40 km / h, will be completed in 1 hour and 30 minutes.
[Setting]
Put the 40 of the outside scale with the SPEED INDEX (MPH) on the inner scale. The "1:30" on the inner scale (time scale) corresponds to 60 on the outer scale. Consequently, the total number is 60 km away.
4) Fuel Consumption Rate
[Example]
We are looking for the individual consumption (liters / hour) with a total consumption of 35 liters in 5 hours.
[Setting]
Put the 35 on the outer scale with "5:00" on the inner scale (time scale) the same. The SPEED INDEX (MPH) on the inner scale corresponds to 70 on the outer scale. Consequently, the fuel consumption is the hour at 7 liters.
5) Fuel consumption
[Example]
We are looking for the total consumption of a single fuel consumption of 6 liters / hour in an elapsed time of 5 hours.
[Setting]
Put the 60 of the outer scale with the SPEED INDEX (MPH) on the inner scale. "5:00" on the inner scale (time scale) corresponds to 30 on the outer scale. Consequently, the total consumption is 30 liters.
6) Estimated duration
[Example]
We are looking for the estimated term when the usage rate, the hour is 5 liters and the total consumption is 30 liters of fuel.
[Setting]
Put 50 on the outer scale with the SPEED INDEX (MPH) on the inner scale. The 30 on the outer scale corresponds to "6:00" on the inner scale (time scale). The estimated duration is thus 6 hours.
Navigation calculations for the flight Sports
1) Time required
[Example]
We are looking for the time needed for the flight at 160 knots for 240 nautical miles.
[Setting]
Put the 16 of the outside scale with the SPEED INDEX (MPH) on the inner scale. The 24 on the outer scale corresponds to "1:30" on the inner scale (time scale). The sought time is 1 hour and 30 minutes.
2) Speed
[Example]
We are looking for the air velocity in a flight of 250 miles, which is covered in 1 hour and 40 minutes.
[Setting]
Put the 25 on the outer scale with "1:40" on the inner scale (time scale) the same. The SPEED INDEX (MPH) corresponds to 15 on the outer scale. The air speed is thus 150 knots.
3) removal of the air route
[Example]
We are looking for the distance at a speed of 180 knots and a flight time of 40 minutes.
[Setting]
Put the 18 of the outer scale with the SPEED INDEX (MPH) on the inner scale. The 40 of the inner scale corresponds to 12 on the outer scale. The removal of the air gap is therefore at 120 nautical miles.
4) Fuel Consumption Rate
[Example]
We are looking for the consumption rate (gallons / hour) of a total consumption of 140 gallons to a flight of 40 minutes.
[Setting]
Put the 14 on the outer scale to 40 on the inner scale. The SPEED INDEX (MPH) on the inner scale corresponds to 21 on the outer scale. Consequently, the consumption rate is the hour at 210 gallons.
5) Fuel consumption
[Example]
We are looking for the total consumption at a consumption rate of 240 gallons / hour in a flight of 1 hour and 40 minutes.
[Setting]
Put the 24 of the outer scale with the SPEED INDEX (MPH) on the inner scale. The "1:40" on the inner scale (time scale) corresponds to 40 on the outer scale. Consequently, the total consumption is 400 gallons.
6) Estimated flight time
[Example]
We are looking for the estimated flight time at a consumption rate of 200 gallons / hour and a filling of 1400 gallons.
[Setting]
Put the 20 of the outer scale with the SPEED INDEX (MPH) on the inner scale. The 14 on the outer scale corresponds to "7:00" on the inner scale. Thus, the estimated flight time is 7 hours.
Conversion
1) Distance
[Example]
The Convert 45 miles into nautical miles and kilometers.
[Surgery]
Put the 45 on the outer scale on the STAT on the inner scale. The display NAUT on the inner scale corresponds to 39 nautical miles on the outer scale and KM on the inner scale corresponds to 72 km on the outer scale.
2) Weight
[Example]
The Convert 16.4 oil lbs. in US gallons and IMP. Gallons and liters.
[Surgery]
Set 16.4 on the inner scale with OIL LBS the display on the outer scale. The US GAL on the outer scale corresponds to 2.2 US gallons on the inner scale, the IMP. GAL on the outer scale corresponds to about 1.8 IMP. Gallons on the inner scale, and LITERS on the outer scale corresponds to about 8.3 liters on the inner scale.
3) Quantity
[Example]
The Convert 13.1 fuel pounds. in US gallons and IMP. Gallons and liters.
[Surgery]
Set 13.1 on the inner scale the FUEL LBS on the outer scale. The US GAL of the outer scale corresponds to 2.2 US gallons on the inner scale. The IMP. GAL on the outer scale corresponds to about 1.8 IMP. Gallons on the inner scale, and LITERS on the outer scale corresponds to about 8.3 liters on the inner scale.
4) Fuel
[Example]
The Convert 16.8 US gallons into IMP. Gallons and liters.
[Surgery]
Insert the 16.8 on the inner scale to the US GAL on the outer scale. The IMP. GAL on the outer scale corresponds to the 14 IMP. Gallons on the inner scale, and LITERS on the outer scale corresponding to 63.5 liters on the inner scale.
