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 provide support to the tube bundle To reduce the induced vibration in the tubes To increase the tube side heat transfer co-efficient by inducing turbulence To increase the residence time of shell side fluid To provide support to the tube bundle To reduce the induced vibration in the tubes To increase the tube side heat transfer co-efficient by inducing turbulence ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it. The ligament efficiency is given by (ph - dh)/ph (ph - dh)/dh (ph - dh . dt/2)/ph (ph - dt)/ph (ph - dh)/ph (ph - dh)/dh (ph - dh . dt/2)/ph (ph - dt)/ph ANSWER DOWNLOAD EXAMIANS APP
