6. (25 points) Water at standard atmospheric conditions flows through a 100 m long plastic pipe with a circular cross section of diameter D = 0.2 m at an average velocity of 10 cm/s. The flow exits into the atmosphere. The pipe material is smooth and has essentially no roughness. What is the pressure at the pipe entrance if it is horizontal? What is the pressure at the pipe entrance if the elevation increases by 50 cm? A Moody diagram...

Water at 20° flows in pipeline system shown below (Fig. 1) at rate of 32400 Vhr. Pipe 1 is 15m long and 0.044 m outer diameter and pipe 2 is 100m long and 0.034m outer diameter. The thickness of both pipes is 2mm. Pipe I is a ductile iron uncoated pipe and pipe 2 is ductile iron coated pipe. There are totally 4 elbows in the system (two elbows in each pipe) and the elbows are 90° street elbows. All...

Water with a velocity of 5m/s flows through the parallel concert piping system with a relative roughness of 0.04 shown below. The entrance diameter is 4m, the length of the parallel pipes is 40 m and L/d for the pipes at A and B is 10m. Here the pressure at the inlet of the system is measured by a mercury manometer directly below it. Given your understanding of the flow of incompressible fluids,notice the squared inlet edge and four standard...
