Estimate (a) the maximum, and (b) the minimum thermal conductivity values (in W/m-K) for a cermet that contains 76 vol% carbide particles in a metal matrix. Assume thermal conductivities of 30 and 67 W/m-K for the carbide and metal, respectively.

The answer is below

Explanation:

Given that:

Volume of carbide () = 76% = 0.76, Volume of Nickel () = 100% - 76% = 24% = 0.24, thermal conductivities of carbide () = 30 W/m-K and thermal conductivities of meta. () = 67 W/m-K

a) The maximum thermal conductivity is given by:

Max =

b) The minimum thermal conductivity is given by:

Min =

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
