Heat generally flows
WebHeat generated in pipes or in orifices due to fluid friction in high-viscosity fluids can be substantial. In the present analysis, the heat generated in steady-state and fully … WebIn the present analysis, the heat generated in steady-state and fully developed pipe flows is investigated for fluids of different viscosities. The pressure drop in a pipe due to fluid friction, ΔP, is generally defined as the product of the fluid friction factor, f, non-dimensional length of the pipe, L∕D, and kinetic energy of the fluid, pV m 2 ∕2, flowing in it.
