Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of a horizontal tube evaporator. 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 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 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design The centre to centre distance between two consecutive baffles in a shell and tube heat exchanger is called the baffle pitch or baffle spacing, which is more than 1/5th the I.D. of the shell. Which of the following is not a function of the baffles? To increase the residence time of shell side fluid To reduce the induced vibration in the tubes To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence To increase the residence time of shell side fluid To reduce the induced vibration in the tubes To provide support to the tube bundle To increase the tube side heat transfer co-efficient by inducing turbulence ANSWER DOWNLOAD EXAMIANS APP
