Filtration tests with a given slurry have indicated that the specific cake resistance (Y is 157 h2/lb. The fluid viscosity is 2.5 lb/(h)(ft), and 3 lb of dry cake is formed per cubic foot of filtrate. The cake may be assumed to be non-compressible, and the resistance of the filter medium may be neglected. If the unit is operated at a constant pressure drop of 5 psi, what is the total filtering area required to deliver 30 ft3 of filtrate in 1/2 h?
A large CSTR, small CSTR and PFR of fixed volume are available. In general, how wouldyou arrange them for getting maximum conversion forreactions of order >1 and1 arrangement is PFR followed by small CSTR followed by large CSTR tomaintain the reac..
Calculate the mass of the liquid (the difference between the total mass of the graduated cylinder plus the liquid and the mass of the empty graduated cylinder).
A thermocouple enclosed in a 3.2mm stainless steel sheath (e = 0.6) is inserted horizontally into a duct to measure the air temperature inside. The walls of the duct are at 650o C, and the true air temperature is 560o C. What temperature will be in..
Propane in the feed to the unit and 80% of the pentane fed to the unit. The mole fraction of butane in the distillate is yB ? 0.4 . The bottom stream contains all of the hexane fed to the unit. Calculate the distillate and bottoms streams flow rate a..
Discuss the applicability of each model - Does it differ based on the interactions you would expect for each model. Can you conclude that one of the models is 'better' than the others from your graphs/analysis in Problems 3.1-2?
Figure shows a simple heat-exchange system. A feed stream is heated by heat exchange in a plate exchanger and then further heated in a steam heater before entering a fixed-bed reactor. The product from the reactor is cooled in the plate exchanger ..
Using the results of part (a), show that the electrons will fail to reach the second plate if (see the attached file for the equation) where -e and m are the charge and mass of an electron.
Combustion of table sugar produces CO2(g) and H2O(l). When 1.46 g of table sugar is combusted in a constant-volume (bomb) calorimeter, 24.00 kJ of heat is liberated.
on a cold winter day the temperature is 2 c and ... Question On a cold winter day the temperature is 2 C and the relative humidity is 15%. You inhale air at an average rate of 5500 mL/min and exhale a gas saturated with water at body temperature (..
Van Laar equation to calculate activity coefficients, How do I use the Van Laar equation to calculate an activity coefficient for an equilibrium ethanol/water binary system with mole fractions of ethanol in liquid of
If 199 atoms of bohrium-267 could be synthesized, how much time would elapse before only 11 atoms of bohrium-267 remain? What is the expected electron configuration of elemental bohrium?
One compartment is evacuated, the other contains steam at 7.5 bar, 300 °C. The latches are removed and the gas expands to fill the entire volume of the cylinder. When the system reaches equilibrium, its pressure is 1 bar. Determine the final tempe..
