Run 90 seconds per lap. More realistically, your first lap should probably be under 85 seconds, try to keep your first two laps under 3 minutes, don't slow down or get discouraged in your third lap, and give it all you've got in the last lap, especially the last 100 meters.
There is no such thing as the last any numbers. Numbers go on forever.There is no such thing as the last any numbers. Numbers go on forever.There is no such thing as the last any numbers. Numbers go on forever.There is no such thing as the last any numbers. Numbers go on forever.
Actually many people may not know it but the last number EVER IN THE WHOLE WORLD is google
the last even number before 900,000 is 899,998
When rounding to the nearest 10, you look at the last digit and if it is greater than or equal to 5, then you add one to the next to last digit and make the last digit 0. If it is less than 5 then you simply make the last digit 0. Thus 393 rounds to 390 while 395 becomes 400.
An ML6 oxygen cylinder, when "charged" to normal pressures, holds 170 liters of oxygen. How long that will last depends on a number of factors. If the flow is set to 2 liters per minute continuous then it will last less than 1 and 1/2 hours. If an oxygen conserving device is used (they give the gas in pluses when breaths are taken) it can last over 4 hours.

Depends on how much pressure is left in the tank.Duration of Flow = Oxygen Tank Conversion Factor * Remaining Tank Pressure (psi) / Continuous Flow Rate (L/min).Conversion factor for D Tank = 0.16Assuming you have a full tank 350 liters at 4000 psi flowing 5L/minDuration = (.16*4000)/5 = 12.8 minutes
One with less than 500 litres!
Depending on the flow rate. A G tank holds 5,300 liters of Oxygen. so just divide that buy the rate you are setting it to flow at. A non-rebreather at 15 lpm should last you close to 6 hrs. normally though the tank should be refilled before it gets down to around 200 psi, just to be safe.
This will depend upon the gas flow rate. A size E oxygen cylinder in the UK contains 680 litres of compressed gas. At a flow of 10L/min for medical emergency use the cylinder will therefore last 68 mins. However if used at 6L/min it will last nearly 2 hours. In the US we use PSIG (gauge level). at full a tank is about 2200 PSI on any given tank size, and the E cylinder has a tank factor of 0.28. So you take take the PSI and multiple it by by the tank factor and divide that number by the flow rate. So at full, 2200 x 0.28 = 616 and dvided that by the flow rate. The final number is the total number of minutes at the given flow rate. So at 2 liters per minute (2 lpm) a completely full E cylinder will last 308 minutes or 5.13 hours (divide total minutes by 60 to get hours). 140 minutes at 4lpm, and so on. You deffinetly want to call your oxygen supplier well before the guage gets to the red. With most guages the very start of the red line (the end farthest from empty) is around 500 PSI. A good rule of thumb is to round down to the nearest whole hour when figuring duration. So when I've needed to I look at 5.16 hours and say 5 hours. If you do run out or are into the red already, call 911 (or your local emergency service), all ambulances carry oxygen and better to have them arrive and use their O2 than to call your oxygen service because ambulance should be able to get their faster. Remember, at the very beginning of red (500 PSIG) a E cylinder will only last 140 divided by flow rate...so 70 minutes at 2lpm, 35 minutes at 4lpm, etc. Dont risk it, when in red, call 911 first, then your oxygen supplies...that is as long as you dont have any other cylinders to use. common tank factors: H Cylinder factor is 3.14 D cylinder factor is 0.16 (typical portable oxygen size) * in the USA, all oxygen tanks, when completely full, are 2200 PSI, if you know the tank factor, you can easily compute the duration. Calculating liquid oxygen is a whole nother ball of wax....
A person can last 4 minutes without oxygen, longer in extreme cold. It takes that long for the body to use up the oxygen in the blood.
last minute
That is the correct spelling (with hyphen) of the adjective "last-minute."
No way of telling w/o knowing the pressure in the tank at the start and the flow rate.
