Which of the following is true according to Pascals principle?
pressure in a fluid is greatest at the walls of the container holding the fluid
pressure in a fluid is greatest at the center of the fluid
pressure in a fluid is the same throughout the fluid
pressure in a fluid is greatest at the top of the fluid
How does a liquid differ from a gas?
a liquid has both definite shape and definite
volume, whereas a gas has neither
a liquid has a definite volume, unlike a gas
a liquid has a definite shape whereas a gas has a definite volume
What is the function of directional control valves?
they are used to control flow rate
they are used to regulate pressure in the system
They are used to influence the direction of fluid flow
they allow flow only in one direction
What is the function of single acting cylinder?
Are a device that will give rotational motion when supplied by air
Used to Control the Air supply to the system and increase efficiency
Used to convert the pressure energy to mechanical energy (linear force in two directions)
Used to convert the pressure energy to mechanical energy (linear force in one direction only)
What is the function of double acting cylinder?
Are a device that will give rotational motion when supplied by air
Used to Control the Air supply to the system and increase efficiency
Used to convert the pressure energy to mechanical energy (linear force in two directions)
Used to convert the pressure energy to mechanical energy (linear force in one direction only)
When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This fact is called________.
Pascal's Principle
Newton's Principle
Archimedes' Principle
Bernoulli's Principle
Liquids take the same ________ and _________ as their container.
shape and size

A force of 400 N acts over an area of 25 m2. Calculate the pressure exerted.
a) 16 Pa b) 25 Pa
c) 400 Pa d) 10,000 Pa
16 Pa
25 Pa
400 Pa

Which statement correctly describes pressure?
the applied force that acts on an object
force per unit area
the area to which a force is applied
force times surface area
This is the relationship between area and pressure
As area increases, the pressure increases
As area increases, the pressure decreases.
As area decreases, the pressure decreases
They have no effect on each other
