Heat Transfer For turbulent flow in a tube, the heat transfer co-efficient is obtained from the Dittus-Boelter correlation. If the tube diameter is halved and the flow rate is doubled, then the heat transfer co-efficient will change by a factor of 1 37 1.74 6.1 1 37 1.74 6.1 ANSWER DOWNLOAD EXAMIANS APP
