Air is to be heated by passing it across the tubes of an in-line tube bundle consisting of 8 rows of 25 mm OD tubes in the direction of flow and 10 tubes in each row normal to the flow. Air approaches the tube bank in the normal direction at 30 °C and 1 atm with a mean velocity of 10 m/s. The tube spacing is 37.5 mm in both parallel and normal to the flow. Calculate the heat transfer from the bundle per m of length when the tube surface temperature is 90 °C.
In the final stages of production, a pharmaceutical is sterilized by heating it from 25 to 75°C as it moves at 0.21 m/s through a straight thin-walled stainless steel tube of 12.7-mm diameter. A uniform heat flux is maintained by an electric resistance heater wrapped around the outer surface of the tube. If the tube is 10 m long, what is the required heat flux? If fluid enters the tube with a fully developed velocity profile and a uniform temperature profile, what is the surface temperature at the tube exit? Fluid properties may be approximated as p = 1000 kg/m³, c, = 4000 J/kg-K, µ = 2x 103 kg/s-m, k = 0.8 W/m-K, and Pr = 10. Determine the required heat flux, W/m². q! = i W/m? Determine the surface temperature at the tube exit, in °C. i °C S,0

Blue and yellow streams of paint (each with a density of 1.6 slugs/ft³ and a viscosity 1500 times greater than water) enter a pipe with an average velocity of 9 ft/s as shown in the figure below. Would you expect the paint to exit the pipe as green paint or separate streams of blue and yellow paint? Explain. Repeat the problem if the paint were "thinned" so that it is only 10 times more viscous than water. Assume the density remains the same, and the temperature is 60°F. Classify the flow. Splitter Laminar Yellow Blue Laminar flow has mixing only by molecular diffusion. Turbulent flow has mixing due to large scale fluctuations. Reynolds number is a measure of whether flow is laminar or turbulent. Classification of viscous flow as laminar or turbulent dictates how the flow is analyzed. What is the Reynolds number for the flow with a viscosity 1500 times that of water? Re= 2 in. What is the entrance length for this Reynolds number? le= ft Green? 25 ft
Give me your thoughts in the inverse proportionality between bulk velocity of a liquid flowing inside a pipe and its friction factor (and consequently, its skin friction energy loss). Effectively, for a fixed pipe length and diameter, the Fanning friction factor and the head loss due to friction decreases as the bulk velocity of the liquid increases. Explain this phenomena scientifically.
