A 18 kW, 900 r.p.m. motor drives a centrifugal pump at 290 r.p.m. by means of a leather belt. The pulleys are of cast iron and are 1.2 metre centre distance. The pulleys of diameter less than 150 mm should not be used. The coefficient of friction between the leather belt and the cast iron pulley is 0.35, and the mass of the belt is 9 kg/m width/m length. The maximum permissible tension per mm width of the belt is 10 N. The drive is to be designed for 20% overload. Blower driven by electric motor Determine the pulley diameters, the required width and length of the belt. Also find the initial tension with which the belt is to be mounted on the pulleys.
