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. 38 16 28 19 38 16 28 19 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In most of the shell and tube heat exchangers, the tube pitch is generally __________ the tube diameter. 2.5 times 1.25-1.50 times One-fourth of Less than 2.5 times 1.25-1.50 times One-fourth of Less than ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design For a cylinderical vessel of moderate height, the weld joint efficiency for joints parallel to the cylinderical axis is given as 1.0, while for joints along the girth (circumference) it is given as 0.8. In calculating the shell wall thickness using code formula for an internally pressurised cylinderical vessel, what value of weld joint efficiency should be used? 1 0.8 0.9 (0.8)0.5 1 0.8 0.9 (0.8)0.5 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, the clearance of the tube is generally More in case of triangular pitch as compared to the square pitch tube layout Not less than one-fourth of the tube diameter or 3/16" Equal to the tube diameter More than the tube diameter More in case of triangular pitch as compared to the square pitch tube layout Not less than one-fourth of the tube diameter or 3/16" Equal to the tube diameter More than the tube diameter ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes Are less prone to fouling None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are easier to clean Are less prone to fouling None of these Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less Are easier to clean ANSWER DOWNLOAD EXAMIANS APP
