WebDec 13, 2024 · Explanation: Biot number: It is defined as the ratio of internal conductive resistance offered by the body to the external convective resistance. \(Bi=\frac{\frac{L}{kA}}{\frac{1}{hA}}=\frac{hL}{k}\) Biot number properties: Biot number is used as a criterion for lumped heat analysis.; Low biot number values signify that the … Webis called the Fourier number (Fo). • hL/k is the Biot number (Bi). • The one-dimensional transient heat conduction problem in a plane wall can be expressed in nondimensional form as (4–12a ...
Heat Transfer: Ch 5 Flashcards Quizlet
WebThe Biot number (Bi) is the ratio of the solid heat conduction thermal resistance to its convection heat transfer thermal resistance, which reflects the distribution law of the temperature field inside an object under unsteady-state heat conduction, and can be expressed as (1) Bi = hl ... The Biot number (Bi) is a dimensionless quantity used in heat transfer calculations, named for the eighteenth-century French physicist Jean-Baptiste Biot (1774–1862). The Biot number is the ratio of the thermal resistance for conduction inside a body to the resistance for convection at the surface of the body. … See more The Biot number is defined as: $${\displaystyle \mathrm {Bi} ={\frac {h}{k}}L}$$ where: • $${\displaystyle {k}}$$ is the thermal conductivity of … See more • Convection • Fourier number • Heat conduction See more The value of the Biot number can indicate the applicability (or inapplicability) of certain methods of solving transient heat transfer problems. For example, a Biot number smaller … See more An analogous version of the Biot number (usually called the "mass transfer Biot number", or $${\displaystyle \mathrm {Bi} _{m}}$$) is also used in mass diffusion processes: See more graphic design management software
