I NEED HELP PLEEEASEEE DUE TODAY Take some time to research a utility plant. If there is one in your area, you may even visit it. Otherwise, look up a type of plant that produces energy - such as a nuclear power plant, a hydroelectric plant, or a coal-burning plant. Find out what energy resources are brought into the plant. Then find out what energy and what “waste” is produced by the plant. Describe how the two Laws of Thermodynamics apply to what you find out in your research. Be thorough. You will be using the information you gather to engage in a debate with your class about thermodynamics.

Zirconium has an hcp crystal structure and a density of 6.51 g/cm3. (a) what is the volume of its unit cell in m3? (b) if the c/a ratio is 1.593, compute the values of c and a.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

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.
