In a particular air flow over a heated surface, the boundary layer temperature distribution is approximated as u y T T T T s s 1 exp Pr where y is the distance normal to the surface and the Prandtl number is 0.7. If T[infinity] = 400 K, Ts = 300 K, and u[infinity]/ν = 5000 m-1 , what is the surface heat flux?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).
