The odor threshold of 4-chlorophenol is 30 ppmv (i. e. 30 ul of 4-chlorophenol per liter of air).
if you have 10 l of water in equilibrium with 2 l of air. you plan to adjust the ph to meet odor threshold of 4-chlorophenol and target ph 6 or 10.

which ph should you choose? pka and h of 4-chlorophenol is 9.4 and 6.27x10" atm m3/mol.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
