: If The Prandtl Number Of A Fluid Is Much Less Than One Momentum Is Transferred More Efficiently Than Heat O Momentum A 1 (9.26 KiB) Viewed 45 times

: If The Prandtl Number Of A Fluid Is Much Less Than One Momentum Is Transferred More Efficiently Than Heat O Momentum A 2 (9.19 KiB) Viewed 45 times

: If The Prandtl Number Of A Fluid Is Much Less Than One Momentum Is Transferred More Efficiently Than Heat O Momentum A 3 (5.67 KiB) Viewed 45 times

If the Prandtl number of a fluid is much less than one, Momentum is transferred more efficiently than heat. O Momentum and heat are transferred almost at the same rate. Momentum is transferred less efficiently than heat. OIt is likely that this is a heavy/viscous ail.
The dominant mechanisms of momentum and energy transfer in a turbulent boundary layer is, O The large-scale motion of chaotic mixing of fluid parcels O Transpiration. O Higher viscosity. Molecular mechanisms.
The friction coefficient Ct is defined as, The dimensionless heat transfer rate. O The dimensionless pressure drop. The dimensionless shear stress, O A function of Pr.
