dc.description.abstractThe object of this thesis was to determine water film coefficients and condensing steam film coefficients for a single tube heat exchanger. A shell and tube apparatus was constructed and these coefficients were determined by Wilsons graphical method. Test runs were made at various pressures and water velocities. It was determined that for flow through a horizontal tube the water film coefficient closely approximates 416 V<sub>w</sub>^0.8 Btu/hr-ft²-F, where V<sub>w</sub> equals water velocity in feet per second, and the Reynolds number lies between 17,000 and 100,000. It was also found that an average condensing steam film coefficient for filmwise condensation was 2000 Btu/hr-ft²-F. It was discovered that this coefficient is much higher if the condensing surface is highly polished.en
