Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of a horizontal tube evaporator. It is unsuitable for concentrating those liquids, which form a scale or deposit salt Liquor flows inside the tube, while the steam is outside submerging the tube Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is suitable for process, in which the final product is a liquor instead of solid It is unsuitable for concentrating those liquids, which form a scale or deposit salt Liquor flows inside the tube, while the steam is outside submerging the tube Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is suitable for process, in which the final product is a liquor instead of solid ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a double pipe (concentric) heat exchanger, the hydraulic radius for heat transfer (for a fluid flowing through the annulus) would be D₂ - D₁ (D₁ and D₂ are I.D. of inner and outer pipes respectively) Same as that for fluid flow More than that for fluid flow Less than that for fluid flow D₂ - D₁ (D₁ and D₂ are I.D. of inner and outer pipes respectively) Same as that for fluid flow More than that for fluid flow Less than that for fluid flow ANSWER DOWNLOAD EXAMIANS APP
