A direct current of 1A flows through a doped silicon water with a amm² cross-section. The...
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...
