A tubular shell/tube exchanger is operated with the following conditions: **neglect viscosity correction Thermal conductivity of the tube wall, is 26 btu/hr-ft-F tube Do = 0.75 inches ; Di =

0.62 inches%3D The exchanger contains 694 tubes which are 14 ft long The number of tube-side passes is2 The tube-side flowrate is 170000 lbs/hr The bulk tube-side fluid temperature is 125F Tube-side fluid properties are: cp1btu/lb-F viscosity = 1.21 lb/ft-hr specific gravity = 1 thermal conductivity = 0.375 btu/hr-ft-F%3D What is the tube-side mass flux, G, lb/hr-ft2? What is the tube-side reynolds number, Nre? What is the tube-side prandtl number, Pr? What is tube-side heat transfer coefficient, hi, btu/hr-ft2-F?
