CORRECTION Pressure Drop and Heat Transfer Prediction for Total Condensation inside a Horizontal Tube, M. D. Razavi and E. K. Clutterbuck, Ind. Eng. Chem. Process Des. Dev. 1980, 19, 715. Page 717. The following section should be inserted. Nomenclature A = inside surface area, mz D = inside tube diameter, m G = condensate mass flow rate at exit, ke: s-l m-2 h, = average condensation heat transfer coefficient, W m-2
