Cooling system

The pump pushes cold water through the pipe to the top of the tower. Here, the water leaves the pipe through small holes. It's like a cold shower. Hot air enters the tower through the air inlet. The shower of cold water flows the air. The cool air then sinks to the bottom of the tower. The cool air enters the house, and then it flows around. It out of the house and into the solar chimney. The sun heats the chimney, and the hot air rises. The hot air finally leaves the chimney through the air outlet.

Parts, functions and locations

Exhaust pipe: exhaust system is usually piping used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove.The combustion gases outside.

Pipeline:Carries the gasoline from de fuel tank to the engine.The pipeline is at the front of the car, below of the engine.

Drive shafts: Transmit torque and rotation.The drive shafts is at the front of the car, below of engine.

Engine: Convert energy into mechanical motion.The engine is at the front of the car.

Fuel gauge: Indicate the level of the fuel in the tank.The fuel gauge inside of the car on the dashboard.

Fuel Tank: Store the gasoline.The fuel tank is at the back of the car, above the brake.

Brake: Used to stop and decrease the velocity of the car.The brake is at the back of the car, below the fuel tank.

Product comparison

A)                                                                                                         B)

1.-The multi-tool A has a ruler, but it doesen't have an awl.

2.-The multi-tool B has a wood saw, but it doesn't have a bottle opener.

3.-The multi-tool A has a wire crimper, but it doesn't have a v-cuter.

4.-The multi-tool B has a opener, but it doesn't have a 1/2 serrated blade.

5.-The multi-tool A has a 14" drive, but it doesn't have a nail file.

Conclussions

My conclusion will be that if you want to buy a multi-tool the best is the first option because is more complete.

Report

We have implemented 5 LEDs on the outside of the house, inside we have 7 led, and both the outside and inside are the same type of LEDs and connect four engines we became fans and the ultimate device for this presentation add pressure sensors, we also made a Breadboard one volt-ammeter with different scales for measuring our demotic system.

We are pleased that we accomplished what was thought from the beginning and we can connect our circuits and control manually through a disposer outlet.

We implement various activities in the project because we had to do all the physical part of the model and have everything in order for when the day of the presentation and everything worked as planned from the beginning.

We still need to finish the program to manipulate the computer by all devices in our system individually, complete the portfolio of evidence, daniell stack that works well for us and give us the voltage we need to turn our emergency system.

Email symbols

@


The at-sign, @, normally read aloud as "at", also commonly called the at symbol or commercial at, and less commonly a wide range of other terms, is originally an accounting and commercial invoice abbreviation meaning "at the rate of" (e.g. 7 widgets @ £2 = £14). It was not included on the keyboard of the earliest commercially successful typewriters, but was on at least one 1889 model[5] and the very successful Underwood models from the "Underwood No. 5" in 1900 onward. It is now universally included on computer keyboards. The mark is encoded at U+0040 @ commercial at (HTML:@).
