What is the average mean temperature for the problem, T=? Show by calculation (5P) m-0.5 kg/s Tm-20C b. Is this flow laminar or turbulent? Show by calculation. (5 P) Tmo T-150 C D-0.05 m c. Is this flow hydrodynamically fully developed? Show by calculation. (5 P) d. Is this flow thermally fully developed? Show by calculation. (5 P) e. What is the average Nu for this flow? Calculate. (5 P) f. What is the average heat transfer coefficient h for this flow? Calculate. (5P) g. What is the exit mean temperature of this fluid? Calculate. (5 P) h. Do you think that your result correct? Explain. (5 P) L=25m i. Calculate the mean fluid temperature Tm (x) at different axial locations along the tube (x=5, 10, 15, 20) and plot the variation (35 P) j. Find the pressure drop (5 P) k. (Optional 10 P) If the mass flow rate was 25 times higher than that of the given value, how would you study the problem? Describe the solution steps. DO NOT SOLVE, JUST DISCUSS!
