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Estimate the work of separation if the feed solution is liquid at 39.250C and the products are withdrawn at the same temperature.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
You have two identical containers at a fixed temperature. In one you have water vapor (H2O) and in the other you have carbon dioxide (CO2). In the high-temperature, classical limit for vibrations and rotations, meaning that (rotation angle
The efficiency of a 400-kVA, single-phase, 60-Hz transformer is 98.77% when delivering full-load current at 0.8 power factor, and 99.13% with half rated current at unity power factor.
Consider 1 mole of ideal gas at 1 bar and 300 K, which of the following statements is true? The absolute entropy of the system is negative. Helium (m=4 amu) will have a larger entropy than argon (m=40 amu).
What is the compressibility exponent for the cake if the resistance of the filter medium is negligible?
Calculate the power factor for which the voltage regulation becomes zero on full load.
Calculate the magnitude of the electric field at the ball's location due to the charged wall, and state its direction relative to the coordinate axes shown.
Assume that the system behaves according to Raoult's law. The saturation pressures of pure acetone and nitromethane at 110 °C are 463 kPa, and 132.4 kPa respectively.
Neglecting stator resistance and rotational and stray-load losses, and assuming constant rotor resistance, calculate the starting torque and the maximum torque in per-unit of full-load torque, as well as the slip at which the maximum torque occurs..
what are the 95 percent precision limits for total flow, and the 95 percent confidence interval for total flow?
Is this a reasonable value from a physiologic point of view? Would the patient be considered normal or diabetic?
Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 g/cm3. How much sodium carbonate was required for complete neutralization of the spill, and how ..
1 kg of liquid water, initially at 40 °C, 2 bar, is heated under constant pressure. If the amount of heat added is 1200 kJ, determine the final temperature and the phase of the system in the final state (if vapor-liquid mixture, report the mass fr..
