OSERVATIONAL EXPERIMENT: RESONANCE FREQUENCY OF AN RLC CIRCUIT. Rubric items for evaluation: B1, B2, B3, B4, B7, B9 You have determined how the voltage across and current through circuit components in an AC circuit relate, depending orn the circuit component. You've seen how V and I relate differently for a resistor, capacitor, and coil (inductor). Now, let's put all these components together to investigate the behavior of an RLC (resistor-inductor-capacitor) circuit. In this experiment, you will determine the resonance frequency of an RLC circuit experimentally.
Design an experiment to determine the resonance frequency of the RLC circuit. Use schematics and diagrams as needed. Put any relevant diagrams or important procedures on the whiteboard as well.

As part of an industrial process, air as an ideal gas at 10 bar, 400k expands at steady state through a valve to a pressure of 4 bar. the mass flow rate of air is 0.5 kg/s. the air then passes through a heat exchanger where it is cooled to a temperature of 295k with negligible change in pressure. the valve can be modeled as a throttling process, and kinetic and potential energy effects can be neglected. (a) for a control volume enclosing the valve and heat exchanger and enough of the local surroundings that the heat transfer occurs at the ambient temperature of 295 k, determine the rate of entropy production, in kw/k. (b) if the expansion valve were replaced by an adiabatic turbine operating isentropically, what would be the entropy production? compare the results of parts (a) and (b) and discuss.
