A belt drive is used to transmit power from an electric motor to a compressor for a refrigerated truck. The compressor must still operate when the truck is parked and the engine is not running. The 50-hp electric motor is rated at 150+X rpm (where value of X = 50), and the motor sheave diameter is 5+d1 in. (where value of d1 = 5). The compressor sheave has 8+d2 in (where value of d2 = 5) diameter. The center distance of the drive is 15 in. Determine the appropriate industrial V belt size, the length of belt, operating speed of compressor and belt speed.
