A rotary drum filter with a filter area of 200 m^2 and a vacuum pressure of 75 kPa is to be used to remove cells from a fermentation broth. Filter leaf tests have been performed on the fermentation broth. The following characteristics were determined:Viscosity (μ) = 5 cPSpecific cake resistance (alpha) = 1 x 10^11cm/g Medium resistance (rm) = 1 x 10^-8 cm^-1 Cake solids per volume filtrate (C) = 15 g/L
It is desired to operate the rotary drum filter with a cycle time of 45 seconds and a cake formation time of 10 seconds.1) What is the filtration rate expected for this system? 2)How significant is the medium resistance?

Magnesium has three naturally occurring isotopes, 24Mg (isotopic mass = 23.9850 amu, abundance 78.99%), 25Mg (isotopic mass = 24.9858 amu, abundance 10.00%), and 26Mg (isotopic mass = 25.9826 amu, abundance 11.01%)
At 20 degrees C the vapor pressure of pure methanol (CH3OH) is 89.0 torr and of pure water (H2O) is 17.5 torr. A solution of methanol and water has a total vapor pressure of 52.9 torr at 20 degrees C.
An automobile engine requires a carburetor or fuel inector to mix the fuel with air. The fuel and air must be mixed in a particlar ratio to achieve maximum efficiency in the combustion of the fuel.
If the sample contains a combined total of 1.50 mol and has a total mass of 45.0g, what are the percentages of CO2 and Ne in the sample by mole?
