You are running an experimental fixed-bed adsorption column that enables you to sample the liquid along the length of the bed. These samples then may be analyzed for solute concentration. Based on your analysis, you determine that 60% of the bed comes to equilibrium with the feed solute concentration at breakthrough. Required:
a. What is the corresponding bed efficiency (fraction of bed utilized)?
b. If the bed performance described above was achieved under conditions where the adsorption isotherm is roughly linear with K = 100, can q be improved to 0.95 by changing K if all else is held constant? Explain.
c. How does the slope of the breakthrough curve change with K? Discuss this issue

with regard to fixed bed adsorption column operation and performance.

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg. a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
