Question: Computer analysis of Prob. with qg == const and Constant .lfluid properties: Calculate the flow, starting with initial conditions of flat velocity and temperature profiles at the inlet. Compare the computer results with the analytical results.

Problem: Consider a 1.25 cm inside-diameter, 1.8 m long tube wound by an electric resistance heating element. Let the function of the tube be to heat an organic fuel from 10 to 65°C. Let the mass-flow rate of the fuel be 0.126 kg/s, and let the following average properties be treated as constant:

Pr = 10

ρ = 753 kg/m³

c = 2.100 kJ/(kg . K)

k = 0.137 w/(m.K)

μ = 660 μPa . s

Calculate and plot both tube surface temperature and fluid mean temperature as functions of tube length.
