Mechanical Engineering

Exhaust gases exit a combustıon test rig at 600°C and flow at0.1 kg/s along a 5 m length of 4 cm-O.D.2 mm wall-thickness steeltube suspended from the roof of the laboratory.An estimate of thetube wall temperature is required for an ambient temperature of22°C.Assume that the inside and wall resistances are not negligible,take into consideration the inside and wall resistances.and thatthe heat loss from the outside is by natural convection andradiation (ε=0.9 for the tube surface)(Hint first show that thegoverning equatıon for this single steam exchanger can betransformed into the equatıon solved by LUMP.Than use LUMP toobtaın the desired result)
