A standard AC motor, generating 10 horsepower at 1,800 revolutions per minute (rpm), is employed to operate a blower at 900 rpm through belt drive mechanisms, illustrated in Figure Q3. The driver and driven pulleys have diameters of 10 cm and 25 cm, respectively, with a center-to-center distance of 80 cm. Fan sheave damater Figure Q3 Motor sheave dameter a. Derive the equation for determining the length of the belt in open belt drive systems. b. Calculate the required belt length for transmitting motion from the AC motor to the blower. c. Consult Table 3 for Micro-VAT's belt catalog, and choose the most appropriate belt number for transferring motion from the AC motor to the blower in this specific application.
