Domagoj Posted February 27, 2016 Share Posted February 27, 2016 If we have 2 Tanks. Tank 1 is on the hill, and Tank 2 is on the bottom of the hill. They are connected, is it possible that whole water doesnt go to the Tank 2. And can someone explain to me hydraulic grade line, head loss, and energy line.

pzkpfw Posted February 27, 2016 Share Posted February 27, 2016 Is the bottom of tank 1 above the top of tank 2? Is the outlet in tank 1 above the bottom of tank 1? Link to comment Share on other sites More sharing options...
Endy0816 Posted February 27, 2016 Share Posted February 27, 2016 Headloss is energy lost as the fluid flows. Friction and bends in the pipe are big sources. Might help to imagine something more viscous is in the tank instead of water. Link to comment Share on other sites More sharing options...
Domagoj Posted February 28, 2016 Author Share Posted February 28, 2016 Bottom of tank 1 is above the top of tank 2. Outlet is going from the bottom of tank 1, diagonaly to the bottom of tank 2. The thing I want to find out....is there a way for those two Tanks to be connected so they are both full... Is that even possible and I would like if someone can explain what exactly head loss mean and is it connected with my problem. Link to comment Share on other sites More sharing options...

That's absolutely possible, as long as tank 2 doesn't leak, and the tank and pipes can handle the pressure. Essentially, you can think of it as one single tank, that happens to have a complicated shape. Link to comment Share on other sites More sharing options...
Domagoj Posted February 28, 2016 Author Share Posted February 28, 2016 I m not an expert in these things so correct me if I m wrong..Head is the height of the water in a Tank... Does head loss mean that that height is lowered so that Tank in the bottom of the hill can have water in it, without the water being spilled out of the bottom tank. lets say the tanks are open and water can go out Look at this drawing (dont mind the text in the picture)...Is it possible that water stays that way and doesnt go out through the lower tank Link to comment Share on other sites More sharing options...
pzkpfw Posted February 28, 2016 Share Posted February 28, 2016 (edited) Note the word "discharge" in the 2nd bullet point. Water is flowing, at 0.5 m^3/s. Energy is lost as the water flows through pipes, and through that constriction, but nothing in that picture is going to keep the water in the top tank. * Edit: * That is, unless the height elevations of the water does become equal. In the diagram, it's not certain that the bottom of A will always be above the top of B. And, they are asking for the elevation of B, at the time when the flow is as noted. They are not implying the heights are static. Edited February 28, 2016 by pzkpfw Link to comment Share on other sites More sharing options...
Domagoj Posted February 28, 2016 Author Share Posted February 28, 2016 Yeah i know it is a very simple question but i was not familiar with those terms energy and hidraulic grade line, i thought there is something more here than simple logic.

derek w Posted February 28, 2016 Share Posted February 28, 2016 Put a float valve in the bottom tank,that will shut off when full. Link to comment Share on other sites More sharing options...
