Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should Preferably flow inside the tube for its easier internal cleaning Perferably flow outside the tube Flow at a very slow velocity Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Preferably flow inside the tube for its easier internal cleaning Perferably flow outside the tube Flow at a very slow velocity Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Tube wall thickness depends on the cor-rosiveness of the fluids and their operating pressure & temperature and is specified by Birmingham wire gauge (B.W.G)-a number which varies from 8 to 18 with the numbers 14 and 16 being more commonly used. Outside diameter of tubes varies from about 15 to 50 mm; however a tube of less than __________ mm outside diameter is generally not recommended for fouling fluids. 28 38 19 16 28 38 19 16 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 300 and 500 180 and 300 45 and 75 5 and 10 300 and 500 180 and 300 45 and 75 5 and 10 ANSWER DOWNLOAD EXAMIANS APP
