A mixture of benzene and toluene are to be separated in a flash tank. The pressure in the flash tank is 800 mm Hg. The units for Antoines equation are mm Hg and ◦C for pressure and temperature, respectively. xB(Psat B) + (xT)(Psat T) = P
log10(Psat B) = 6.905 − (1211/ (T + 221))
log10(Psat T) = 6.953− (1344/ (T + 219 ))
At what temperature should the tank be operated to get the highest purity toluene in the liquid phase (maximizing xT)?

Suppose we have a byte addressable computer that has a 32-byte cache with 8 bytes per block. the memory address is 8 bits long. the system accesses memory addresses (in hex) in this exact order: 6e, b9, 17, e0, 4e, 4f, 50, 91, a8, ab, ad, 93, and 94. (a) assuming the cache is direct mapped, what memory addresses will be in cache block 2 after the last address has been accessed? (b) assuming the cache is direct mapped, what is the hit ratio for the entire memory reference sequence given, assuming the cache is initially empty? (c) assuming the cache is 2-way set associative with a lru replacement policy, what is the hit ratio?
