Heat Transfer The overall heat transfer co-efficient for a shell and tube heat exchanger for clean surfaces is U0 = 400 W/m².K. The fouling factor after one year of operation is found to be hd0 = 2000 W/m².K. The overall heat transfer co-efficient at this time is 894W/m².K 287 W/m².K 1200W/m².K 333W/m².K 894W/m².K 287 W/m².K 1200W/m².K 333W/m².K ANSWER DOWNLOAD EXAMIANS APP
