WebFeb 25, 2024 · A rule of thumb that incorporates pipe size is to choose liquid lines to handle a velocity of 1.5 +d/10 where “d” is the pipe diameter, inches. This gives 1.6 m/s for 1-inch and 2.5 m/s for 10-inch piping, and about 20 kPa/100 m pressure drop. Similarly, gas lines can be sized for 20d m/s and steam lines 35 m/s (maximum). WebDescription. The Elbow (G) block models flow in a pipe turn in a gas network. The block calculates pressure losses due to pipe turns, but omits the effect of viscous friction. You can model a smoothly curved or sharp-edged pipe elbow by setting the Elbow type parameter to Smoothly curved or Sharp-edged (Miter) , respectively. jeffrey\\u0027s archery https://holistichealersgroup.com
