I am hoping I can get some help from your expertise.
I am currently using two small diaphragm air compressors connecting with a Wye-fitting and that will be the main air source for a spray nozzle. The outlet of the Wye-fitting will be connected to a nozzle, which has a very small hole in order...
Hi all,
I have a simple question regarding to the heat transfer of a heated water tank with three scenarios
First scenario:
Air velocity, 88 ft/s at -20 F, is blowing parallel to a 8' x 16' cylindrical tank filled with water. The tank is 1/4" cold-rolled steel without any insulation. The tank...
Hi,
I am sure there are tons of books out there on designing rotary vane compressor. Can any one recommend me a couple of them? I am looking for more of engineering and design guidelines of rotary vane compressor head specifically. Anything other than the books is also helpful. Thanks a bunch.
Is there a clear source where I can refer to for protecting my own design from the company I work for? It sounds kind of strange why I ask this. If I do the design work in the company but nothing has been manufactured yet, will the design still be the company's property? I would like to know my...
Hi, All
Is there a way to create a flange on the tab from a cylindrical sheet metal? I could have created a part for extrution but it won't let me flat the part for the strip machine to bunch it out. Your file's link is...
Hi, Everyone
Is there a textbook or a website that I can study about the behavior or airflow pattern?
The idea is simple: using a blower/fan on one end of a pipe with a deflector (blade/propeller) in the middle and creating whirl airflow pattern. In other word, pressurized air is forced into a...
This question is specifically focus on siphon air atomizing nozzle, which creates atomization with compressed air. When compressed air enters the nozzle, it creates suction and draws liquid for atomizing process.
Since compressed air is the only driving force for siphoning the fuel and the...
Hi everyone,
I have posted this thread recently, but I guess I have put it in the wrong section and I hope I can get some answers here.

I understand this is very fundamental. I am working on a small low pressure boiler design. To find out what...
Hi everyone,
I understand it sounds very fundamental. I am working on a small low pressure boiler design. To find out what the BTU output is, I am familiar with Q=m*cp*delta_T. The water inlet and outlet temperatures have been measured as well as the water flow rate. This will give you a...
Hi Engineers,
I have searching an analysis for this "Y" fitting configuration. Consider two inlets and one outlet. Assuming fluid is water and the fitting has the same diameter on all three ports. I can simply write and equation Q_outlet = Q_inlet1 + Q_inlet2. Can I use energy equation to...
Hi all,
Please let me briefly explain the scenario of this experiment
Types of fluids: Air and Diesel
Types of measurement: flow rate and pressure
Air pressure : regulated in 10 to 15 psi
Both of air and diesel fuel are working in 1/4" ID pipe/hose.
A spray nozzle is placed into a...
Hi all,
My company has come across a situation of corrosion pitting inside of the stainless steel tank right along the weld. The welding materials is 316L SS welding rod to weld 304 SS sheetmetal.
The application of the tank is to heat up different liquids in the tank and transfers heat for...
Hi all, recently join the eng-tips forum here
I have a question regarding to the outlet temperature of a heat exchanger.
A standard set up of a fan and a radiator like in a car system. The fan is behind the radiator to draw the cold air to the radiator to heat up a room. As far as I know...
hi guys,
I have a little chamber in my backyard. Recently, i have dug out an old 1000 Watt air heater and installed in the cabin.
I like to find out how long i need to run the heater to warm up to the room temperature of 21 ºC from the ambient of 12 ºC. Either the heater needs to be bigger...
