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.

A Day Full of Fluid Mechanics

You have a 9:40 class, but you feel sick. Maybe all

you need is a pain reliever, but who knows...

4/21

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.

You turn the TV on to get morning news. Nothing

good again :-(

Fluid mechanics is involved in countless

military/defense applications.

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.

7/21

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.
