35 HEAT TRANSFER PMU-101 Fall 2018Dep Q-3 Gas at 120°C enters a 5-em diameter pipe at an surface temperature of the pipe is 60°C. Determine supposed to leave the pipe at 86°C. average velocity of 1.6 m/'s. The h when the gas is pi length when ine the pipe i. Assume Fully Developed Flow ii. Check whether the assumption length with the calculaspio of part i is correct by comparing the entrance length with the calculated pipe length If the assumption is not correct, determine the actual exit temperature i ise of the gases iii. for the same length. 30 Points The properties of hot gases: 0.5664 kg/m , ; k " 0.04721 Wim.K: v. 5.475 x 10-5 m'/s; C,- c, oS6Jkg.K: Pr 0.6937
