Question
A circumferential fin on a pipe of 50 mm od is 3 mm thick and 20 mm long. thermal conductivity = 45 w/mk. convection coefficient = 100 w/m2k, base temperature = 120°c surrounding fluid temperature = 35°c. determine the (i) heat flow and effectiveness (ii) if the pitch is 10 mm, determine the increase in heat flow for 1 m length of pipe. also determine the total efficiency.
answer
circumferential fin on a pipe of 50 mm OD is 3 mm thick and 20 mm long.
Thennal conductivity k =45 w/m.C, convection coefficient h =100 w/m^2.C,
basc temperature 120 C and surrounding fluid temperature 35 C. Determine (a) heat
flow and effectiveness (b) if the pitch is 10 mm, determine the increase in heat flow
for 1m length of pipe. Also determine the total efficiency.
