Question: Computer analysis of Problem with q"s = const and constituted properties: Calculate the flow, starting with initial conditions of flat velocity and temperature profiles at the inlet. Compare, the results.
Problem: Consider a 0.6 cm inside-diameter. 1.2 m long circular 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 1.26 x 10-3 kg/s
Pr = 10
ρ = 753kg/m3
c = 2.092 kJ/(kg.K)
k = 0.137 W/(m.K)
μ = 0.00065 Pa . s
Calculate and plot both tube surface temperature and fluid mean temperature as functions of tube length. What is the highest temperature experienced by any of the fluid?
