Wikipedia says 26.3% at 0 degrees C and 26.4% at 15.5 deg C. So very little variation, if wikipedia can be relied on.
take 15gallons of ice from -15deg f to 140deg f
from some of web address i have got an empirical formulae that density @ 15deg celcius minus (-) 0.0011 is equal to weight reduction factor used for quantifying liquids on mass basis at atmospheric pressure conditions.
From the service manual: At 5deg C/40 deg F or higher: SAE20W40 Type SE At 15deg C/60 deg F or lower: SAE10W30 Type SE My preference: Castrol pure synthetic. You'll be amazed at how much smoother the bike shifts.
Depends on your climate conditions. Assuming that the conditions don't get much lower than -15deg celsius, then 33 percent antifreeze should be adequate. purchase 2litres of antifreeze and pour into 4litres of water, drain and refill radiator - BUT LET THE ENGINE TICK OVER WITH THE RADIATOR CAP OFF for a while to get rid of airlocks. Six litres should be adequate for most cooling systems, but if you have serious cold, then 50 percent would be advisable.
Specific heat of Copper metal: Values given are in gram-calories(15deg) per gram per degree centigrade. To convert to joules per gram per degree Centigrade, multiply by 4.185 At given temperature in degrees Celsius, specific heat is: T: minus 253 : S.H. 0.0031 minus 253 to minus 153 : 0.0245 minus 213 : 0.029 minus 193 : 0.047 minus 188 to plus 20 : 0.0788 minus 79 to plus 18 : 0.0883 zero C : 0.0909 plus 20 : 0.0912 plus 15 to plus 100 : 0.09305 plus 50 0.0928 plus 100 : 0.0942 plus 200 : 0.0963 plus 900: 0.1259 Hope this helps * 1 year ago Lange Handbook of Chemistry
