    The motor pulley rpm is read from the motor data plate. Using a ratio the blower rpm can be found. To solve any ratio such as this one simply remember to cross multiply and divide. In this problem cross multiply the 1750 times the 8 to get 14000. Divide the 14000 by 16 to get 875 rpm. The RPM of the blower is 875.
