Answer to Question #163761 in Mechanical Engineering for Johan Nieuwoudt

Question

A pump is driven by an electric motor running at 1145 rpm and the speed of the compressor is 920 rpm. If the diameter of the motor pulley is 160 mm, calculate the diameter of the pump pulley

Answer 1

Speed of motor = 1145 rpm

Diameter of the motor pulley = 160mm

Speed of the compressor = 920rpm

Diameter of the compressor = xmm

$\dfrac{1145}{160} = \dfrac{x}{920}$

$x = \dfrac{1145×920}{160}$ = 6584mm
