A batch reactor produces \(1 \times 10^7\) kg of a product per year. The total batch time (in hours) of the reactor is \(k \sqrt{P_B}\), where \(P_B\) is the product per batch in kg and \(k = 1.0\) h/\(\sqrt{kg}\). The operating cost of the reactor is Rs. 200/h. The total annual fixed charges are Rs. \(340 \times P_B\) and the annual raw material cost is Rs. \(2 \times 10^6\). The optimum size (in kg) of each batch (adjusted to the nearest integer) is
