An amplifier has a gain of 10 and follows a bandpass filter where the loss in the center of the bandpass is 0.05. What is the combined gain/loss of the two cascaded blocks at the center frequency of the filter?

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
