Hello,
I am currently doing some scoping work to identify potential storage sites for a reservoir capable of holding 500,000m3 of water. The terrain in the area has a fairly consistent fall, however there are some humps and hollows around.
I am trying to optimize the reservoir geometry to...
Hi,
This is a relatively simple one I believe, but I have not had to do it before.
I am trying to work out what the velocity will be through a 150mm pipe which is 45m long and has an RL difference of 5m from top to bottom.
The pipe is pressumed full with 100mm of head above the top of the pipe...
Hello,
We have recently had a pipeline checked for wear and I wan't to determine what the maximum amount of wear (or reduction in wall thickness) before the pipe must be replaced.
We are using ASTM A53B 12" Sch 80 steel pipe with a wall thickness of 12.7mm.
The maximum pipe pressure seen in...
Hi,
We are currently in process of designing a new pipeline. We wish to pump to a height of 56m (over a hill) and then the pipeline will go down the other side approximately 131m. Therefore the line will be under vacuum and I am worried the line will compress inward (as it is HDPE pipe). Is...
Hi,
I am trying to determine the pressure drop across a pipe reduction, from 6" pipe to 1" pipe. The volumetric flow rate is 4.5m3/min.
Is there a k value for a reduction of this size? or is there an equivalent length for a reduction in pipe of this magnitude?
I would like to see how the...
Hi,
I am looking for a reference/information of temperatures of various types of metal on metal sparks.
I need to know roughly what the temperature of a spark is which is generated during contact of diffent metals.
If anyone can help with this that would be great.
Thanks in advance.
Hi,
I am trying to determine the hydraulic diameter of a finned tube but I am unsure how work this out. I have attached a diagram showing the tubes and dimensions. The distance between the ends of the fins is 0.5mm. If someone could help with this simple problem that would be great.
Hi,
I am trying to find some good online sources for designing finned tube heat exchangers. The best source I have so far is "Compact Heat Exchangers, W.M.Kays and A.L.London", which is very good however it is quite a brief text.
There seems to be very few examples for designing this type...
Hi,
I am designing a heat recovery system for a milk powder spray drier. I will be utilising waste exhaust heat (67degrees C 245T/hr) and use it to pre heat the inlet air to the drier.
The drier inlet air is supplyed at 35degees C where it is then heated to 205degrees C by an air heater...
