Develop a mass balance for a continuous diafiltration step and indicate the volumetric flow rates and concentrations of different species in the different streams obtained.
Determine the primary to secondary ratio of the line-to-line voltages and the line currents.
Define what is meant by the numerical aperture and explain why the lens is oil filled. Using the Rayleigh Criteria, define the smallest resolvable features when light of wavelength 633 nm is used to illuminate the substrate and the oil filled obje..
A process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional select..
A sealed rigid tank of 1 m3 capacity contains 1.2 kg of water at 1 bar and 99.63 °C. To this tank we add heat until the pressure increases to 3 bar. What is the temperature at the end of the heating?
