Pressure drop-flow rate curves for superheated steam in U-tubes were generated. Forward flow of hot steam is favored in the longer and taller U-tubes. Reverse flow of cold steam is favored in short U-tubes. Steam generator U-tube bundle geometry and tube diameter are important. Need for correlation development for natural convention heat transfer coefficient.
