Water at 20 o C enters the 4 cm-diameter, 14 m-long tube at a rate of 0.8 kg/s. The surfacetemperature of the pipe is maintained at 165 o Cby condensing geothermal stream at the shellside of the heat exchanger. Use water properCesat 85 o C for all calculaCons.(a) Show that the water flow is turbulent and thermally fully developed. (b) EsCmate the heat transfer coefficient for convecCve heat transfer from the pipe to the water. For a fully developed turbulent flow within the smooth pipe, the Nu number can becalculated from the following equaCon:(c) Calculate the exit temperature of the water. (d) Share your opinion on whether the use of water properties at 85°C is appropriate. Yes or No because:
Consider a hot automotive engine, which can beapproximated as a 0.5-m-high, 0.40-m-wide, and 0.8-m-long rectangular block. The bottom surface of the block isat a temperature of 100°C and has an emissivity of 0.95.The ambient air is at 20°C, and the road surface is at25°C. Determine the rate of heat transfer from the bottomsurface of the engine block by convection and radiationas the car travels at a velocity of 80 km/h. Assume theflow to be turbulent over the entire surface because of theconstant agitation of the engine block. a) Calculate convective heat transfer coefficient (h). b) Calculate the total heat transfer rate

- A very thin metallic sheet is placed between two wood plates of different thicknesses. Theplates are firmly pressed together and electricity is passed through the sheet. The exposed surfaces ofthe two plates lose heat to the ambient fluid by convection. Assume uniform heating at the interface.Neglect end effects and assume steady state.[a] Will the heat transfer through the two plates be the same? Explain.[b] Will the exposed surfaces be at the same temperature?
