Process Equipment and Plant Design When one of the fluids is highly corrosive and has fouling tendency, it should Perferably flow outside the tube Preferably flow inside the tube for its easier internal cleaning Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Flow at a very slow velocity Perferably flow outside the tube Preferably flow inside the tube for its easier internal cleaning Flow outside the tube, when the flow is counter-current and inside the tube when the flow is co-current Flow at a very slow velocity 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 tube side heat transfer co-efficient by inducing turbulence To provide support to the tube bundle To increase the residence time of shell side fluid To reduce the induced vibration in the tubes To increase the tube side heat transfer co-efficient by inducing turbulence To provide support to the tube bundle To increase the residence time of shell side fluid To reduce the induced vibration in the tubes ANSWER DOWNLOAD EXAMIANS APP
