Question

Difference between equivalent diameter for annulus for heat transfer and preesure drop

Answer 1

Explanation:

Specific heat = 0.9989 Btu/(lb. ... It is important to note that the equivalent diameter for heat transfer is different from that calculated for pressure drop. Outside diameter of the smaller tube, do = 1.5 in = 0.125 ft. Inner diameter of the outer tube, Di = 1.834 in = 0.1528 ft.
