Answer / bikram saw

main difference is velocity difference ,blower velocity is higher than fan and blade of blower wider than fan

Answer / vimal.

Fan is electronic device, it works magnetostruction effect.
Blower is used to send out high pressure air from compressor

Answer / arindam dhara

Fans, blowers and compressors are differentiated by the method used to move the air, and by the system pressure they must operate against. As per American Society of Mechanical Engineers (ASME) the specific ratio - the ratio of the discharge pressure over the suction pressure - is used for defining the fans, blowers and compressors
Fans Specific Ratio Presser rise upto 1.11
Blowers Specific Ratio Presser rise Upto 1.11 to 1.20
Compressors Specific Ratio Presser rise Upto more then 1.20

Answer / pb

A blower is the complete assembly of the fan, the housing to direct the air, and the drive motor to produce high pressure winds.

Fan is used for distribution of air over larger span and to produce low pressure winds.

why we use kg/cm2 instead of kg/m2 as a unit of pressure. As we know kg is a MKS unit and cm is a CGS unit. So why we use combination of both(kg/cm2)while describing the pressure.
