An equimolar binary liquid mixture (comprised of components ‘1' and ‘2') is to be processed through a flash evaporator maintained at 10 bar and 3500K. The vapour stream leaving the flash vessel contains 60mol% of ‘1'. At the given flash temperature and pressure the following conditions hold. 1 2 1 2 1 For the vapour phase: ln ; For the liquid phase: 1.3012 Pure liquid phase fugacity: 8.0 E mix L G y y x x RT f bar ?
(i) Estimate the ratio of molar stream flow rates L/V exiting the flash chamber
(ii) Compute the pure liquid phase fugacity for component ‘2
A Hollow steel sphere contains 100 watt electrical filament inside it for heating. The other relevant data are as follows- Internal and external radius of the sphere = 0.24 and 0.32 m respectively.
If the temperature at the time of measurement is 20°C above ambient, compare the percent error of both meters when measuring a current of 5 A.
Consider a diatomic gas, N2, at 298 K. This gas is compressed reversibly and adiabatically from 15 dm3 to 5.0 dm3. Assume that the heat capacity of this gas is CV=5R/2, and that it behaves ideally. Calculate the final temperature, T2, of the gas.
Suppose that both diodes have Rf = 10 Ω and Von = 0.5 V. Find the revised values of the resistors and voltage sources (v1 and v2) in order to accomplish the same objective.
The pressure is adjusted so that 75% of the mixture is vapor while the temperature remains at 55 °C. Determine the pressure and the compositions of the two phases.
On the same graph plot temperature, ignoring the effect of conduction, which assumes linear variation with time. Comment on your findings in relation to diffusion time found in problem 10.
Calculate the mass of the metal in gr than can be prepared from 150 grams of aluminum and 250 grams of iron (iii) oxide
The curie (Ci) is a commonly used unit for measuring nuclear radioactivity: 1 curie of radiation is equal to decay events per second (the number of decay events from 1 g of radium in 1 s).
Assume negligible miscibility between the aqueous and organic liquids in each other, and ignore any change in density on removal or addition of the enzyme to either stream.
The time-average value of the induced voltage. (e) The induced voltage when the plane of the coil is 30° from the vertical.
A sealed tank contains saturated steam at 5 bar. The volume of the tank is1m3. Heat is added until the pressure in the tank pressure doubles. What is the final temperature?
Gas Absorption and Transfer Operations: Column Diameter Calculation, A gas absorption column to handle 3630 kg/hr of a gas is being designed. Based on pressure drop, entrainment and foaming considerations
