The V-belt is used to deliver 7.5 kW of power at 1440 rpm from the electric motor to the fan which rotates at 480 rpm and works 24 hours a day. The transmission shaft distance is 1 m. The load correction factor (Fa) is known to be 1.3 and the type of V-belt cross-section is type B with a pitch distance correction factor (Fc) of 1.08 and an arc of contact (Fd) correction factor of 0.94. The diameter of the driving pulley is 200 mm and the driven pulley is 600 mm. Calculate: pitch distance (L) actual/corrected transmission shaft distance (C) arc of contact angle power rating per belt number of belts required

Question
The V-belt is used to deliver 7.5 kW of power at 1440 rpm from the electric motor to the fan which rotates at 480 rpm and works 24 hours a day. The transmission shaft distance is 1 m. The load correction factor (Fa) is known to be 1.3 and the type of V-belt cross-section is type B with a pitch distance correction factor (Fc) of 1.08 and an arc of contact (Fd) correction factor of 0.94. The diameter of the driving pulley is 200 mm and the driven pulley is 600 mm. Calculate:
pitch distance (L)
actual/corrected transmission shaft distance (C)
arc of contact angle
