K
Zero K is absolute zero; ice melts at 273 K (0° C, 32° F); water boils at 373 K ( 100° C, 212° F).
"The letter ""k"" when used as a prefix before a unit symbol indicates a multiplier of 103. Symbol of ""kilo"". E.g., k? = 103 ohm, one kiloohm, one thousand ohms. (The symbol is the letter ""k"" followed by the ""Greek capital omega"" letter, some browsers unfortunately do not support this.) "
(K) The
SI base unit of temperature, defined by assigning 273.16 K to the temperature at which steam, ice, and water are at equilibrium (called the triple point of water). The freezing point of water is 273.15 K.
(k) Prefix used in the
SI system meaning "one thousand of". For example 1 km means "one thousand meters" 2.8 kg could also be written "2.8 × 10
3 g" or "2800 g".
(k) A rate constant is a proportionality constant that appears in a
rate law . For example,
k is the rate constant in the rate law d[A]/dt = k[A]. Rate constants are independent of concentration but depend on other factors, most notably temperature.
Cpk, Cp, Cr:
Potential capability (Cp) - This is the simplest and most straightforward indicator of process capability. It is defined as the ratio of the specification range to the process range; using ± 3 sigma limits we can express this index as:C
p = (USL-LSL)/(6*Sigma)Put into words, this ratio expresses the proportion of the range of the normal curve that falls within the engineering specification limits (provided that the mean is on target, that is, that the process is centered).
Non-centering correction (K) We can correct Cp for the effects of non-centering.Specifically, we can compute:K = abs(Target Specification - Mean)/(1/2(USL-LSL))This correction factor expresses the non-centering (target specification minus mean) relative to the specification range. Demonstrated excellence (C
pk). Finally, we can adjust Cp for the effect of non-centering by computing:C
pk = (1-k)*C
pIf the process is perfectly centered, then k is equal to zero, and C
pk is equal to C
p. However, as the process drifts from the target specification, k increases and C
pk becomes smaller than C
p.
Capability ratio (Cr) - This index is equivalent to C
p; specifically, it is computed as 1/C
p (the inverse of C
p).
