Subject: Physics + Economics

Life Cycle Diagram:

1) Consider the provision of hot water using an electric water heater fueled by electricity produced from natural gas in a centralized powerplant. Draw a process flow diagram for this energy service with at least four stages in the supply chain. List at least four social or environmental impacts that result from process and identify where in your diagram the impacts occur.

2) List and describe three weakness of life cycle assessment for evaluating future energy systems, and suggest ONE solution for one of the weakness.

3) List & explain two separate factors that can lead to an energy source having a low Levelized Cost of Energy [LCOE] despite the high capital cost.

Expert Solution

2)Life cycle assessment technique is to assess environmental impacts associated with all the stages of a products life from raw material extraction through materials processing , manufacturing and distribution, disposal or recycling.

Three weaknesses are

1)Over usage of raw materials

2) Causes hazardous to marine life

3) Disposal and recycling.

3) * Usage of solar energy plant in all sectors can be more beneficial from domestic level to industrial level can help the economy of the country and also environmental hazardous.

* Usage of wind power also can help the economy of the country and the environment.1) In the diagram above the use of natural gas is the key product . And by that we can generate electricity and also can form dream.

One more advantage here is the water vapor is directly passed into the environment.

Consider an ideal Rankine cycle using water with a high-pressure side of the cycle at a supercritical pressure. Such a cycle has a potential advantage of minimizing local temperature differences between the fluids in the steam generator, such as the instance in which the high-temperature energy source is the hot exhaust gas from a gas- turbine engine. Calculate the thermal efficiency of the cycle if the state entering the turbine is 30 MPa, 550°C, and the condenser pressure is 5...

Question No 1: The subject ‘economics’ is growing day-by-day and its subject matter can never be rigid. In other words, the definitions of economics must not be rigid. Because of modern research, many new areas of economics are being explored. But, the definitions of economics are still revolving around the four ancient definitions. In this context, answer the following. a) Critically evaluate the four definitions of economics from the modern perspective. [Answer in 240 – 320 words] b) According to...
