Bernoulli's Equation

Why is the top of an airplane wing curved?

• To create an area of low pressure above the wing
• To create an area of high pressure above the wing
• To create equal pressure above and below the wing
• To make the wing look really cool

Think about Bernoulli's Principle.  What do you think will happen when you have running water next to a shower curtain?

• Curtain goes outward from the shower
• Curtain goes in towards the shower
• Curtain stays the same
• Water gets the curtain wet

Bernoulli’s equation is a direct result of

• Law of conservation of mass

• Law of conservation of volume

• Law of conservation of energy

• Bernoulli's theorem

A dam holds back the water in a lake. If the dam has a small hole 1.4 meters below the surface of the lake, at what speed does water exit the hole?

• 1.4 m/s

• 5.2 m/s

• 3.i m/s

• 9.8 m/s

A hose lying on the ground has water coming out of it at a speed of 5.4 meters per second. You lift the nozzle of the hose to a height of 1.3 meters above the ground. At what speed does the water now come out of the hose?

• 1.9 m/s

• 2.5 m/s

• 5.6 m/s

• 3 m/s
