Process Equipment and Plant Design In condenser, the cooling water is passed in the tube side in a pass arrangement, because Pressure drop is reduced It makes condenser compact It reduces heat transfer area More thinner tubes can be used Pressure drop is reduced It makes condenser compact It reduces heat transfer area More thinner tubes can be used 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
Process Equipment and Plant Design Pressure drop due to pipe fittings can be estimated by the equation, ΔP/p = 4f.Le/D.V2/2gc, where, Le = equivalent length of straight pipeline which will incur the same frictional loss as the fitting and D = diameter of the fitting. The value of Le/D (dimensionless) for 45° elbow and 180° close return bends would be respectively around 180 and 300 300 and 500 5 and 10 45 and 75 180 and 300 300 and 500 5 and 10 45 and 75 ANSWER DOWNLOAD EXAMIANS APP
