Materials and Pressure correction Factors: MPF Empirical factors that modified BC and evaluate particular instances of equipment beyond a basic configuration: Uninstalled Cost = (BC x MPF) MPF = Φ Φ (Fd, Fm, Fp, Fo, Ft) Fd: <strong>Design</strong> variation Fm: Construction material variation Fp: Pressure variation Fo: Operating Limits ( Φ Φ of T, P) Ft: Mechanical refrigeration factor Φ Φ Φ ( (T ( evaporator) EQUIPMENT MPF Pressure Vessels Fm . Fp Heat Exchangers Fm (Fp + Fd) Furnaces, direct fired heaters, Tray stacks Fm + Fp + Fd Centrifugal pumps Fm .
