Process Equipment and Plant Design In a shell and tube heat exchanger having triangular pitch, the shell side equivalent diameter is given by (p² - πd²/4)/πd 4(0.86p² - πd²)/πd (4p² - πd²/4)/πd 4(0.86p² - πd²/4)/πd (p² - πd²/4)/πd 4(0.86p² - πd²)/πd (4p² - πd²/4)/πd 4(0.86p² - πd²/4)/πd ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid ANSWER DOWNLOAD EXAMIANS APP
