A solution containing 10mol% of CS2
(1) and 90mole% acetone
(2) is to be separated in a reversible continuous flow isothermal, isobaric separator into pure acetone and an aeotrope that forms at 39.250C under atmospheric pressure. The azeotrope contains 61mole % CS2.
Estimate the work of separation if the feed solution is liquid at 39.250C and the products are withdrawn at the same temperature. At 39.250C, 1 2 604 ; 400 . S S P mmHg P mmHg ? ? Assume t
Two aqueous sulfuric acid solutions containing 20.0 wt% H2SO4 (SG = 1.139) and 60.0 wt% H2SO4 (SG = 1.498) are mixed to form a 4.00 molar solution (SG = 1.213).
Calculate the diffusion flux at 1027(C (1300 K) for the same concentration gradient and assuming an activation energy for diffusion of 125,000 J/mol.

A 184.6-mg sample of K2Cr2O7 is dissolved in enough water to make 500.0 mL of solution. c. A 0.1025-g sample of copper metal is dissolved in 35 mL of concentrated HNO3 to form Cu2 ions and then water is added to make a total volume of 200.0 mL. (C..
To determine the Ksp value of Hg2I2, a chemist obtained a solid sample of Hg2I2 in which some of the iodine is present as radioactive 131I. The count rate of the Hg2I2 sample is 5x10^11 counts per minute per mole of I. An excess amount of Hg2I2(s)..
Determine the kVA rating of the synchronous motor.
A strap, instrumented to measure stretch, is worn around the chest to detect respiration whilst a subject is at-rest. The resulting signal is contaminated by electrical noise from the mains at 50 Hz with a similar amplitude to the respiration sign..
Based on your knowledge of instruments specify two methods to prevent the drying running of a centrifugal pump, if the pump is being used to empty a vessel in an automated process plant.
