If the cost of an equipment of the desired capacity is not available it may be estimated from the cost of another equipment using the formula
A.(cost)1 = (cost)2 [(capacity)2/(capacity)1]
B.(cost)1 = (cost)2 [(capacity)1/(capacity)2]
C.(cost)1 = (cost)2 [(capacity)1/(capacity)2]0.6
D.(cost)1 = (cost)2 [(capacity)2/(capacity)1]0.6
