Hi, Assuming that there is constant inlet of water containing Pb particles into settling tank, water on the outlet is clear (all Pb particles remain in tank), and there is no slurry outlet, I need to estimate volume of lead slurry on the bottom, after certain amount of time. For that I need...

Hi, I need data (x-y graph) for solubility of SO2 in concentrated sulphuric acid (approx. 98%) at temperature approx. 80 deg. C. Can anyone send me this data or give a link/reference? Thanks in advance for any help, Paul PS. If not solubility, it may be partial pressure of SO2 over SO2...

Oops! Of course the flowrates into pipe "I" and "II" shouldn't be the same, but proportional to number of d3 holes in each pipe. Sorry for confusion.

Hi, Thanks for replies Sorry if something was unclear. First, so called "section I and II" are not chambers, but pipes, each with many holes (more than 20). V1 and inlet pressure are known and constant, as well as all pipe system dimensions and arrangement. What I have to do is to, by...

Hi, I have a pipe system as in this picture: The water flows in with flow rate of V1 [m3/s]. I have to adjust diameter of openings in flanges (d1 and d2) so water flows with the same speed through each small hole (diameter d3). There are n1 holes in section I and n2 holes in section 2. How...

Hi, The tank truck (let's assume volume = V)is being filled with 22% Sulfuric acid at temperature 40 deg. C, flow rate = 20 m3/h. Is it possible to estimate, how much vapour (acid mist) will be emited? How to calculate it? Thanks from advance for Your answers.

Hi, I have a vacuum system for sludge draining. The sludge from an open tank (so atmospheric pressure) is drained by rubber hose connected with pipe. Then it goes to liquid-vapor separator and the gas goes to the vacuum pump. 1. Assuming, that there is constant pressure of 0.1 bar abs. in...

How do I draw a tangent line connecting 2 circles with different diameters? Thanks in advance. PS. I use AutoCAD 2004

I meant automatic change of distance from dim. line to object. Let's say that I set it to 20 units. When I print it in 1:1 scale, everything's fine. But when I set Viewport scale to 1:4 and then update dimensions, text, arrows etc. are bigger, but this distance stays the same. So, in my print it...

thanks! that's what I needed. But is it possible to scale this distance?

Is it possible to input distance from dimension line to dimensioned object from keyboard (eg. 20)? I tried to do it after message: "Specify dimension line location or [Mtext/Text/Angle/Horizontal/Vertical/Rotated]:", but i got different distance every time. Also, is it possible to change this...
