· C 1 = cost of Plant / equipment 1 . C 2 = cost of Plant/ equipment 2 . Q 1 = capacity or size of Plant/ equipment 1 . Q 2 = capacity or size of Plant/ equipment 2 . x = powersizing exponent or the costcapacity exponent . One of the model is called sixtenth (6/10) factor rule, according to this rule x = . 3.
