Mechanical Engineering
A steam generator consists of a bank of stainless stell (k=15W/m·K) tubes habing the core configuration of CF7.0-5/8J and aninner diameter of 13.8 mm. The tubes are installed in a plenumwhose square cross section is 0.6 m on a side, thereby providing afrontal area of 0.36 m2. Combustion gases whosepropertires may be aproximated as those of atmospheric air, enterthe plenum at 900 k and pass in cross flow over the tubes at 3kg/s. There are 11 rows of tubes in the gas flow direction. Ifsaturated water at 2.455 bar experiences boiling in the tubes, whatis the gas exit temperature? A convection coeficient of 10.000W/m2·K is associated with boiling in the tubes.
