A: Hydraulics is the study of pressure within liquids

Q: What is pneumatics?

A: Pneumatics is study of gas (often air) under pressurein an enclosed system.

Q: What is barometer?

A: A barometer is a device used for measuring air pressure.

A: Buoyancy is the tendency of objects in fluids to either rise or sink because of density differences along with their surroundings

.[image]

A: Buoyant force is an upward force that is exerted by a fluid. Without it, transportation of nutrient through our bloodstream wouldn't be possible. If the object exerts a greater force downward than the buoyant force, the object will sink. If the object exerts a greater force upwards, the object will rise. If both forces are equal, the object is neutrally buoyant.

A: Sphygmomanometer is a device used to measure blood pressure by applying pressure to the artery in your arm to stop the flow of blood for a short period of time. [image]

A: The respiratory system is a natural fluid system with a set of organs and passages involved in breathing. When you inhale, your chest expands and creates an area of low pressure in your lungs.

Air then rushes from the higher pressure outside of your body and then moves into the lower pressure in your lungs.[image]

A: Convection is the movement of fluids caused by their differences in density. These movements cause heat to spread evenly through the entire fluid

A: At sea level, the atmospheric pressure is 101.3 kPa or one atmosphere. For every 10m you plunge into the water, the pressure would increase by 1 atm(atmosphere). One atm is equivalent to approximately 100,00 newtons of force pressing on a single square metre.

A: Hydraulic multiplication uses an incompressible fluid in order to increase and transmit a force from one place to another. This is used to elevate vehicles for repair.

A: Hydraulic systems use liquids under pressure to apply force to move something. Pumps are significant parts of a hydraulic system along with tanks or pipes.

[image]

A: Pneumatic systems use gases under pressure to apply a force to move something. Pneumatic systems use a compressor to compress air so that when it builds up and when released, the gas will exert a strong force.

A: The ciruclatory system is a natural fluid system that transports blood throughout our body. The heart acts as a pipe and the blood vessels act as pipelines similar to those in a hydraulic system.

A: The valve is an essential part of a hydraulic system that controls the path of a fluid through a pipe. [image]

A: A fluid has dynamic pressure if it is in motion, this is energy that can be used to carry out tasks, either direct or indirect.

[image]

A: Static pressure can be created by squeezing an enclosed fluid. This fluid can now apply a force although it is not in motion.

[image]

A: Check valves allow fluids to flow in only one direction.

A: Blood pressure is the force of the blood applied on the walls of the vessels. It is an indicator of someone's general health. Blood pressure can be measured with a sphygmomanometer. High blood pressure can harden arteries and possibly cause them to burst. Low blood pressure shows that the heart may have some problems or low water levels. Proper blood pressure can be maintained by having the right amount of water in your system.

A: Asthma is a disease of the respiratory system that causes the pathways to the lungs narrow making it difficult to breathe. Asthma is commonly triggered by cold air, dust, excercise, and stress. An inhaler can help deliver medication to the lungs.
