Estimation of capital
C = F * Sum (C_e) C is the total capital cost, F is the installation factor also known as Lang factor, and C_e is the cost of major equipment. Lang factor is 3.1 for solid processing plant and 4.74 for fluids processing plant. Better estimate can be made when the different factors are used for corresponding equipment.
