Process Equipment and Plant Design Pressure drop (Δp) and the superficial gas mass velocity (G) in case of packed absorption tower operating in the preloading range are related as Δp = G Δp = G0.5 Δp = 1/G0.6 Δp = G2 Δp = G Δp = G0.5 Δp = 1/G0.6 Δp = G2 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 Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
