What is a water footprint? You can show it on a graph or table. What food-consumption patterns or direct water-use habits explain your water footprint? Note: Your income is used to estimate your water footprint from the use of industrial goods. This is not a very exact estimate. Choose a couple of water-intensive foods that you consume and indicate in which countries or regions they are produced. Are these countries or regions water-stressed? Do you think your diet is relevant to water availability in those places? Explain.

We discussed many energy options in this module and the previous module. Taking into account all the energy options we learned about in this course, please discuss the following:

1. In your evaluation, which of the discussed energy solutions benefits our society the most? Please explain.(Solar & Wind
   Biomass & Biofuels
   Fuel Cells & Geothermal
   Power Grid & Efficiency)
2. What values is your evaluation based on?
3. Evaluate the government actions to implement the energy solution you selected. Is the government doing enough? Please explain. Do you have any suggestions to improve the implementation of this solution?

The net power of a combined gas-steam power plant is 450 MW. The pressure ratio of the gas turbine cycle is 14, the air enters the compressor at a temperature of 300 K and the turbine at a temperature of 1400 K. Combustion end gases coming out of the gas turbine produce steam at a waste heat boiler at 8 MPa pressure and 400 degrees Celsius temperature and exit the boiler at 460 K temperature. The steam cycle has an open feed water heater operating at 0.6 MPa pressure, the condenser pressure is 20kPa. Recognizing that all compression and expansion are isentropic;

a)

The ratio of mass flow of air to mass flow of steam,

b)

In the combustion chamber, the air is given to the air in unit time,

c)

calculate the thermal efficiency of the combined cycle.

4-Hydroxyacetophenone has a role as plant metabolite and fungal metabolite. Write the products formed when 4-hydroxyacetophenone reacts with the following reagents. i. (CH3)2CHMgBr followed by H3O+ ii. excess CH3OH, H+ iii. NH2OH, H+ iv. H2/Pt

1. The Hawaiian volcanoes are all part of a chain of islands that have been formed by an intraplate hotspot. The volcanoes of the Big Island, such as Kilauea, are the only ones active now, because the Big Island is currently located on top of the hotspot. Look at the article about Lo'iki seamount. Based on its location offshore from Kilauea, and the fact that Lo'iki has only become active fairly recently, which direction do you think the Pacific Plate is currently moving? Explain your reasoning.
