a) Ammonia converter reactor delivered cost Ksh1.2 million. Factors for installation costs (0.4) and training (0.2) are determined. An indirect cost factor of 0.3 is applied to all direct costs. Estimate total cost.
b) A 100m ^ 2 heat exchange costs Ksh3000 five years ago when the cost index was 130. Estimate the cost of a 300m ^ 2 heat exchange today when the cost index is 255. The exponent for a 300 heat exchanger is 0.9.
