What is the nature of p-v curve for air expansion in a pneumatic cylinder when the temperature is constant?
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.
What is the formula of density of air at particular Temp?
from the equation of state pressure = density * gas constant * temperature
Which statements about series circuits are correct?
series circuits have 1 pathway they have constant current(Amperes) not constant voltage. Resistance=R+R+R+...
What is the different between centrifugal and positive displacement compressor?
compressor work on two principles 1)reduce volume of a constant amount of gas 2)adding more gas in a constant amount of volume positive displacement compressor works on first principle it reduces the volume of gas by applying force on it but gas amount is constant in every stroke or rotation thus increasing the pressure. centrifugal compressor work on second principle it adds more amount of gas in a given constant volume thus the pressure increase.
What is the NAICS Code for Air and Gas Compressor Manufacturing?
NAICS 333912 applies to Air and Gas Compressor Manufacturing.
