Question: Calculate the amount of energy that would come out of the generator if 20,000,000 BTU went into the boiler. The boiler is 81% efficient, the turbine is 43% efficient, and the generator is 98% efficient. Also calculate how much energy goes into the condenser. Save your answer to a Word document and upload to Canvas. It will help if you can show your steps by writing/typing out each step in detail. Follow the steps in the presentation. If you write out the solution by hand instead of typing, you scan the paper and save it as a pdf. file and upload it as an attachment.
Be sure the numbers in the data and the answers all have units. The decimal percents do not have units, of course.
