Study of the Aerodynamic Process and Its Impact on Cotton Transportation Process through the Cotton Pipeline

The article provides a theoretical analysis of the velocity distribution and distribution in the cross section of the pipe during the transportation of cotton. It studied the factors that move air and transport material in a pneumatic pipeline, developed a mathematical model and built graphs. The effect of pressure on the ease of construction of pipes for air transportation of raw cotton and the speed distribution in the process of transporting cotton, as well as the factors that cause pressure loss in the shells of pipes were studied. So, if the expansion after the air pipe is expanded (5), we will introduce K1 = 0 and the beating coefficient . If the current narrows before burdening, then we enter K1 = 1 and the input soften rate from the formula . The air flow is moving upwards below the slope and the longer the pipe is the air flow is so significant (strong). The flow of air is divided into laminar and turbulent streams according to leakage. The procedure for transportation of raw cotton using air will move the turbulent the sidelines, interacts with the layers. If the turbulent passes in a well-round smooth passenger-pipes, the number of critical Reynolds can be delivered to 200,000. The process of transporting cotton in pnevmotransport is far from the laminary regime in far away and stronger mode.
