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 It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres Liquor flows inside the tube, while the steam is outside submerging the tube It is unsuitable for concentrating those liquids, which form a scale or deposit salt It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres Liquor flows inside the tube, while the steam is outside submerging the tube 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 5 and 10 45 and 75 300 and 500 180 and 300 5 and 10 45 and 75 300 and 500 ANSWER DOWNLOAD EXAMIANS APP
