Process Equipment and Plant Design In case of 1.5" heat exchanger tubes, the inside flow area __________ with decrease in BWG. Decreases Increases Remains same None of these Decreases Increases Remains same None of these ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, the overall heat transfer co-efficient is proportional to the tube side (volumetric flow rate)0.8. This is valid, only when the ratio of the tube side film resistance to the total resistance is almost equal to 20.8 2 ∞ 1 20.8 2 ∞ 1 ANSWER DOWNLOAD EXAMIANS APP
