Viral meningitis: Meningitis caused by many viruses is usually contagious. However, certain viruses that are transmitted by mosquitoes are usually not spread person to person, so they are not contagious.
3] Heat transfers through the glass by conduction 4] Heat transfers from the glass to the outside air via convection. If the temperature differences are small and there are no winds or drafts, transfer of heat to/from air/glass will be by conduction.
Heat transfer to or from a fluid flowing through a tube R. Shankar Subramanian A common situation encountered by the chemical engineer is heat transfer to fluid flowing through a tube. This can occur in heat exchangers, boilers, condensers, evaporators, and a host of other process equipment.emember that the purpose of using a heat transfer coefficient is to calculate the heat flux between the wall and the fluid. In the case of uniform wall flux, we can use an energy balance directly to infer the way in which the bulk average temperature of the fluid changes with distance along the axial direction.
