cost estimating for chemical engineering plant design

Equipment Cost Estimation

#2. Let us have an example, e.g. there is need to estimate the capital cost of a carbon steel centrifugal pump, 200 HP. The table of Perry informs that such a pump of 100 HP (without motor) has a cost of about 4400 $ and an exponent of 0.67. 4400x(200/100)^0.67=7000 $.
