residual head, system curve and pump curve | Eng-Tips When you develop your system curve you simply add the three components, i e static head, friction head and velocity head The pump develops a certain head and does not "care" how you use it A confusing aspect is that the velocity head is usually called an "exit loss", or as you have termed it here a "residual pressure" It becomes confusing because everyone looks to the end of the pipe to

Top Bars AND Other Bars - LAP Splices | Eng-Tips 3 Due to the construction process of a vertical wall, is "Other Bar" applicable to all bars (vertical flexure, vertical temperature, and horizontal tempeature shrinkage bars)? 4 How would you determine if a bar is a "Top Bar" or "Other Bar" for concrete shapes other than horizontal slabs such as a key? Really Appreciate your Help
Top Bar Development Length in conc wall | Eng-Tips Hooks are ineffective in compression, development length of horizontal deformed reinforcing bars in walls are under discussion The lap length splice and end anchorage are the applicable applications, if no compression is possible in the bars under discussion, then hooks would negate the need for top 1 3 factor
Wall Horiz Rebar--Top or Other Bars?? | Eng-Tips The definition of a top bar is any horizontal bar with more than 12" of fresh concrete below it Based on that I have always considered horizontal wall bars as top bars I don't recall a wall bar exclusion
Seismic load, horizontal and vertical | Eng-Tips It is completely separate from ELF, which is a method to compute and distribute horizontal loads If the examples are for ELF loads, they would not be focusing on other loads Other loads would be vertical seismic, dead, live, earth pressure, wind, etc, and would be included in an analysis with load combinations including these loads
