Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of a horizontal tube evaporator. 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 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 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Larger depth of liquid on the trays of a distillation column Leads to high tray efficiency Results in higher pressure drop per tray Neither A nor B Both A & B Leads to high tray efficiency Results in higher pressure drop per tray Neither A nor B Both A & B ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Generally, as the length of the liquid path on a tray is increased beyond 5 ft, the overall column efficiency May increase or decrease depending upon the plate spacing Remains same Increases Decreases May increase or decrease depending upon the plate spacing Remains same Increases Decreases ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design The ratio of lateral strain to linear strain is termed as the Modulus of elasticity Poisson's ratio Bulk modulus Shear modulus Modulus of elasticity Poisson's ratio Bulk modulus Shear modulus 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
