What is the nature of p-v curve for air expansion in a pneumatic cylinder when the temperature is constant?
Wiki User
∙ 13y ago
PV = RT
is the ideal gas law
P-pressure
V-volume
R-gas constant
T-temperature
then the equation becomes
PV = constant
therefore
P = 1/V
pressure becomes inversely proportional to the volume.
hence as the volume increases the pressure decreases.

4 examples of a pneumatic device?
erm.... Pneumatic Drill Pneumatic Cylinder Pneumatic Actuator Pneumatic Switch Pneumatic Nailgun Pneumatic Air gun Pneumatic Launcher Bit more than four, but now you can choose, hope this helps,
What is expansion turbine?
differential expansion is refer to differential distance between rotor blade and fix blade.rotor expand toward generator and casing expand toward control valve.when temperature increase ,expansion in casing and rotor.so rotor mass is less than casing which rotor expand more than casing.
Is fridge compressor good enough to lift 40kg weight using pneumatic cylinder?
a compressor cant lift..
How does stroke and diameter affect pneumatic system?
The performance of a pneumatic system is dependent upon the air displaced or handled, which is directly proportional to the stroke and diameter. In other words, it is to be considered like a cylinder whose volume increases with diameter and length.
What cylinder is better hydraulic or pneumatic?
Strictly speaking, which is better depends on the equipment of which this cylinder is a part of. Pneumatic systems take on slight change in volumes (as air can get compressed on load and reduce in volume) and hence, a big NO for systems where even minute linear movements are critical. Hydraulic systems offer exact displacements. There are other considerations too
What will happen to the pressure inside a cylinder with a piston when its volume is reduced while staying at a constant temperature?
If the volume of the cylinder is reduced while the temperature remains constant, the pressure inside the cylinder will increase. This relationship is described by Boyle's Law, which states that pressure and volume are inversely proportional at constant temperature.

What does a pneumatic cylinder do in autos?
You will usually find a pneumatic cylinder as a shock absorber in an auto. They reduce the amount of bounce that is transmitted to a passenger riding in the car.
What is mean by stroke length in pneumatic cylinder?
the distance the piston moves
When were pneumatic cylinders invented?
The first patent for the pneumatic cylinder was issued in 1940 in the US to Samuel Clegg and Jacob Selvan. Alfred Beach was given a patent in 1865 for a pneumatic subway train using a giant pneumatic tube.
What is the difference between single action actuating cylinder and double acting cylinder?
Single action actuating cylinder means that fail action (open or close) is accomplished by spring mounted on the opposite side of pneumatic cylinder and normal operation by airDouble acting cylinder means that both, opening and closing, manoeuvres are accomplished by pneumatic cylinder.
What is expansion turbine?
differential expansion is refer to differential distance between rotor blade and fix blade.rotor expand toward generator and casing expand toward control valve.when temperature increase ,expansion in casing and rotor.so rotor mass is less than casing which rotor expand more than casing.
The molecules of gas in a cylinder of butane?
The molecules of gas in a cylinder of butane are in constant random motion. They collide with each other and with the walls of the cylinder, creating pressure. The temperature of the gas is related to the average kinetic energy of its molecules.
Which is better to control a pneumatic cylinder- a meter-in flow control or a meter-out flow control?
When a pneumatic cylinder chamber is filled with pressurized air and the air-chamber on the other side of the piston is metered-out by a flow control, the movement or speed of the cylinder is more consistent than to meter-in the pressurized air.
What is the function of a master cylinder compensating port?
Type your answer here... Correct Answer: Allow for the normal expansion and contraction of brake fluid due to temperature changes
What is single acting hydraulic cylinder?
Single-acting devices consist of a large plunger, or piston, into which oil (or air in a pneumatic cylinder) is pumped.
If the volume of a cylinder is reduced from 8.0 liters to 4.0 liters the pressure of the gas in the cylinder will change from 70 kilopascals to what?
Assuming the temperature remains constant, we can use Boyle's Law which states that pressure and volume are inversely proportional at constant temperature. If the volume is halved from 8.0 liters to 4.0 liters, the pressure will double from 70 kilopascals to 140 kilopascals.
