TheTick,
5 minutes in the penalty box is acceptable for idiot sportscasters but not for engineering professionals.
How can speed mean anything other than velocity? Speed is distance per time, velocity. A reference to rates of speed is merely implicating different values of velocity. Come on...
Thank you ivymike for the questions.
Each truck is an exact duplicate of the other. All elevation or section views would look identical. A plan view would be identical. The same tires, mud flaps, the same everything.
Let's consider the turbulence at a distance if a motorcycle was passing...
In discussion with others a question was raised.
On a calm day there are two identical trucks pulling identical trailers at a very high rate of speed. They are on the same road and the distance between the two is far enough to not affect each other. If one truck has a far greater mass than...
Gee Inch,
In the Chemical Process Industries I have worked we were usually interested in a continuous minimum flow. I found minimum flow was needed for several applications. That is why I gave the explanation I did.
I have trained operators in plants to use a pump curve. They found using the...
To perform an analysis of a pump and know what it's capabilities and limitations you need your pump curve. You will be given the rpm and impeller size. You probably know this but your x axis is your flow rate with your y axis you TDH or total dynamic head. For your impeller at zero flow you...
Knowing the NPSHA and the NPSHR coupled with the TDH and your flow rate will get you started at a pump. If you were to have different conditions as posed by changing tank levels thus different NPSHA you can put a VFD to your motor. By decreasing your speed you lower your NPSHR. You will change...
You should have a limit on your pressure drop. That coupled with the efficiency of your bed or what other specs they are giving you for what the bed consists of would give you a diameter and depth of your bed based on your flow rate. That is where I would start.
I don't know what your streams contain but if you want an idea what equipment is available for your volumes and your concentrations of COD, BOD, TSS, TDS and VOC's look at the US Filter web site which is a part of Siemans. You can also go to their website. There are some Technical Reports...
