High pressure Definition and 68 Threads

Hi everyone, I intend to design a high pressure solar central tower boiler/receiver that can output super heated steam. The idea here is that the solar receiver receives about 800Kw of solar radiation and uses it boil water (36C) to about 590C/150bar. My educational background is not...

Hi, I have been toying with the idea of producing electricity from the cross winds that build up in my house. Basically when I leave a window open one one side of my flat and open a window on the other the wind blows through the house very strong. I want to place a wind generator on one...

Hi guys, i got a problem with the high pressure cleaning with the titanium tubes. What happened was that the titanium tubes (SB 338 Gr 12; OD=50,8mm; thickness=0.71mm) experiences scalings with Calcium Sulphate, and now we are trying to clean it off using HP cleaning, the specified max...

Hi there, I was wondering what happens when a great pressure is applied to water. I think that applying pressure to water vapor would turn it into water (liquid) since it has a higher density. So at first I thought that water would turn into ice, but quickly I realized that would be odd since...

Is it possible to get frostbite from compressed air? How does this happen?

I want to calculate the reaction heat in a ammonia convertor but I need some specific heats of N2,NH3,Ar and CH4 at 500°C and 200bar. I could find data at 500°C but not at that pressure. thanks Stefaan

Has anyone out there had any successes or failures on high pressure (up to 400 psi) quick connect connectors? I've done the basics McMasterGoogleGlobalSpec search, and have come up with a few different kinds. There is a large variance in price, so I wanted to see what anyone has had...

Hi! Does anywone knows what happen with ammonia adsorption at pressures of 1-15 bar? thanks.:smile:

I am designing a cracking furnace to crack Ethylene Dichloride. the furnace is at around 500 C and 2 M Pa. To perform an energy balance I need the specific heat capacity of the EDC at the aforementioned temperature and pressure. I can only find it at standard conditions and can find no way of...

My hottub has a leak in its high pressure plastic plumbing. I've replaced what parts I can but am having trouble locating the leak since I have to drain the tub completely to examine it. Can anyone suggest a dye or something that will allow me to locate the leak even after the water is...

this is what I did: I attached a hose to an empty plastic bottle, sealed it with plastic paste and put a cork in it. When i turned the water on the pressure started builiding up. What I noticed was that when it reaches about 2 bar it gets a lot hotter. I don't know why, do you? When the cork...

ok, i have forgotten my thermodynamics, and need a confirmation for my thoughts here...if youd compress He gas by blowing more gas into a thermo-isolated tank, the tank would get hotter right? and after compressing it enough the gas will become fluid (thats not a real phase transition, but you...

Liquid sodium can exist at room temperature at EXTREMELY high pressures. Why?

I'm in the process of designing a high pressure hydrogen compressor. In this machine, an oil will be in direct contact with the hydrogen. To minimize the amount of oil vapor that enters the hydrogen and must be separated, an oil with high molecular weight and low vapor pressure should be best...

hello :-p i want to ask about the deviation of real gases under low temperature and high pressure. :-p my reference book states that carbon dioxide deviates more than nitrogen and hydrogen,this is because the order of boiling points of is decreasing from carbon dioxide to hydrogen.this...

I have interest in an application involving a very high pressure tube. The pressure a pipe can resist is given by the Barlow formula P = 2*S*t/d, with P the pressure, S the tensile strength of the pipe material, t the pipe wall thickness, and d the inner diameter. I want to get maximum...

An enclosed cylindrical* (disc) vessel one inch thick and five inches in radius holding two pounds of fluid at ambient atmospheric pressure (14psi?)and being spun at 30,000 rpm's. Assume the centrifugal force acting on the fluid creates a pressure of 1,000 psi. The question is ... "If the...

What are the applications and advantages/disdvantages of using gas and high pressure chromatography? Why does the pharmaceutial industry use chromatography? Any info would be much appreciated Thanx
