Communicating vessels are devices where two o more vessels with the same or different shapes are communicated at the bottom by another tube.

Communicating vessels are devices where two o more vessels with the same or different shapes are communicated at the bottom by another tube.

Exercise 1 Where are water reservoirs located in a village, at the same, lower or higher lever that houses are Why? http://www.galleryof3d.com/site/gal-profile.php?ID=7

Where are water reservoirs located in a village, at the same, lower or higher lever that houses are

Why?

Answer At a higher level, because as higher the level is higher is the pressure. http://www.bhassoc.com/sec_ww/ww_water_storage.htm

Exercise 2 Why is there the same level of water in the toilet? http://www.commerce.com.tw/products/EN/T/Toilet_Water.htm

Why is there the same level of water in the toilet?

Answer Because it has the level of the higher point of the pipe, as we have seen on the explanation of communicating vessels.

Because it has the level of the higher point of the pipe, as we have seen on the explanation of communicating vessels.

Exercise 3 When do you think the flowers stop being watering? http://www.rittenhouse.ca/asp/product.asp?PG=1016

When do you think the flowers stop being watering?

Answer When the level of the water in the container is at the height of the end of the hose.

When the level of the water in the container is at the height of the end of the hose.

A hydraulic press is a force multiplier. It is a device similar to communicating vessels. It produce a large force from a small one

Exercise 1 Explain how the car brakes work

Explain how the car brakes work

Answer When a force acts on the brake pedal, the pressure is transmitted through the fluid in the pipes and forces the liquid in the pipes against the brake drums on the four wheels

When a force acts on the brake pedal, the pressure is transmitted through the fluid in the pipes and forces the liquid in the pipes against the brake drums on the four wheels

Exercise 2 Which force is smaller, force in or force out? Explain why

Which force is smaller, force in or force out? Explain why

Answer Force in is smaller because the surface of its piston is smaller.

Force in is smaller because the surface of its piston is smaller.

Exercise 3 Explain how a fork lift works

Answer When a force acts on the control lever, the pressure is transmitted through the fluid that makes the fork lift up.

When a force acts on the control lever, the pressure is transmitted through the fluid that makes the fork lift up.
