You wake up in the morning and the room is
comfortably warm. Free convection driven by
the radiator heat the room up all night.
You wash your face. The water first passes
through a flowmeter outside your houseand travel inside pipes before coming to the
faucet.

You decide to do some cleaning beforeheading to school. Fluid mechanics is
involved in proper suction of air and filtering
dust.
You have your breakfast. The coolant moving
inside the tiny pipes at the back of your
refrigerator, and the air circulating inside it are
both fluids.

Weather forecast says it will be a sunny day.
You are lucky being far away from the
hurricanes sweeping the East coast of the
United States.

You get on your car. When you turn the
engine on, the fuel is first pumped fromthe tank, mixed with air, and combustion
gases do work inside the engine.
Unfortunately your plans of traveling with
Ankaray all the way to METU campus
should wait for at least another semester.

Before your class you go to the PC lab and print your homework report. Inkjet
printing and electronics cooling also involve fluid mechanics.

You go to bed after studying for tomorrowsquiz. In your dream you find yourself
in the middle of the ocean, surrounded by a farm of wind turbines. Side effects of
too much ME 305.
