Tab 4/A - Fluid Power & Thermodynamics

Front

What is the formula to convert Celsius to Kelvin?

Back

K = C + 273.15

Front

What happens to water when it freezes in a pipe?

Back

The water expands, causing the pipe to break.

Front

True or False: As molecules heat up, they move from a gas to a liquid.

Back

False. As molecules heat up, they typically move from a liquid to a gas.

Front

What is the relationship between pressure and volume in a gas?

Back

When pressure increases, volume decreases (Boyle's Law).

Front

What is the area of the large piston in the hydraulic system described?

Back

100 square centimeters.

Front

What is the area of each smaller piston in the hydraulic system described?

Back

25 square centimeters.

Front

How do you calculate the total weight supported by the smaller pistons in the hydraulic system?

Back

Total weight = weight on each piston x number of pistons.

Front

If each smaller piston supports 200 grams, what is the total weight supported by 4 smaller pistons?

Back

800 grams.

Front

What principle explains how hydraulic systems work?

Back

Pascal's Principle: Pressure applied to a confined fluid is transmitted undiminished in all directions.

Front

What is the significance of the area of pistons in a hydraulic system?

Back

The area determines the force exerted by the fluid and the mechanical advantage of the system.
