Question

Air at p=1 atm enters a long tube of length 2.5 m and diameter of 12 mm at an inlet temperature of Tm,i=100oC and mass flowrate of 300 x 10-6 kg/s. A constant heat flux is applied to the air from the tube surface. If the tube surface temperature at the exit is Ts,o=180oC, determine the heat rate entering the tube. Evaluate properties at T=400 K.

Answer 1

The heat transfer q = 18.32W

Step-by-step explanation:

In this question, we are asked to calculate the heat entering the tube and also evaluate properties at T =400K
