Part I.

Get familiar with the basics of the Solar Energy simulator by running the basics the site

suggests.

Part II.

Design your experiment to explore the amount of energy that can be provided with this

solar panels-battery system.

Consider the following:

2. Start your exercise with a fully charged battery.

3. With the sun intensity at min (use a value > 0), turn on the all appliances and

measure in what time you run out of battery.

4. Do the same with the sun intensity at 4 and then at max.

5. Turn off some of the appliances and see how the time of battery changes.

6. Let the battery use all the charge (

charge again.

Part III.

1. Plot a graph of Energy available from battery vs. load use, for the three sun

intensities (max, min, 4).

2. Plot a graph of the time it takes for the battery to charge vs. time it takes to run out,

for the three sun intensities (max, min, 4).

3. Briefly discuss the results of the exercise.

### set up and solve a case-study example of the light-intensity distribution in a photochemical reactor.

Photochemical reactor modeling: a case-study problem. Although radiation is important in heat transfer, an analogous model can be used in the design of photochemical reactors. The modeling of these reactors….

### Write a critique on this technique of secondary-emission measurement.

Secondary-emission measurement: a case-study problem. An indirect way of measuring of secondary emission from ponds or large bodies of water used in waste treatment is to measure the concentration and….

### set up a mass transfer model and evaluate the variation of the local mass transfer coefficient at various locations in the plate.

Chemical vapor deposition (CVD) on an inclined susceptor: a case-study problem. An important application of convective mass transfer theory is in CVD processes employed to coat surfaces with thin films….
