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 1 2 ∞ 20.8 1 2 ∞ ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Triangular pitch tube layout as compared to square pitch in a shell and tube heat exchanger Both B and C Facilitates comparatively easier external cleaning because of large clearance Permits the use of less tubes in a given shell diameter Permits the use of more tubes in a given shell diameter Both B and C Facilitates comparatively easier external cleaning because of large clearance Permits the use of less tubes in a given shell diameter Permits the use of more tubes in a given shell diameter ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Mc Cable Thiele method used for finding theoretical stages in a distillation column assumes that the Liquid/vapor loading across the column remains constant Sensible heat differences are small, because the temperature changes from tray to tray is small All of these Trouton's rule is applicable Liquid/vapor loading across the column remains constant Sensible heat differences are small, because the temperature changes from tray to tray is small All of these Trouton's rule is applicable ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Weep holes provided in the plates of a distillation column Facilitate draining out liquid from a tray when the unit is not in operation All of these Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation Facilitate draining out liquid from a tray when the unit is not in operation All of these Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation ANSWER DOWNLOAD EXAMIANS APP
