In magnetic resonance, the time for 63% of transverse relaxation to occur; the value is a function of magnetic field strength and the chemical environment of the hydrogen nucleus; for protons in fat and in water, in a 1.5T magnet, about 60 milliseconds and 250 milliseconds, respectively.he effective T2 relaxation time, shorter than T2 because of magnetic field inhomogeneities; the observed time constant of free induction decay.
Including conversion and generation losses, a single full Leaf charge might take 25 kWh (19 kWh usable into the battery). Factor in expected usage to get an average kWh per month value.
TECHNOLOGY: Electric. BASE MSRP: $28,800. Although Nissanâs all-electric Leaf has been on the market for two-and-a-half years, and returns updated for 2013, many Americans remain unaware of its existence, and others do not have a firm grasp of its pros and cons.
