Dear members:
I plan to make foam concrete for low load structure.
I think of using dish soap as foam agent using home- made foam generator...and i have a Q about what should be the air pressure in such process??
Because i have seen a video on you tube for the famous aircrete Harry on which he...
Dear members:
I have an idea of using water brine solution for freezing plastic water bottles,how practical such design?
I think about using same idea of vapor compression refrigration unit but the evaporator (will not be an insulated room with crazy fans running inside, with the importance of...
Hi guys:
as I understand organic rankine cycle usually uses fluid with boiling temp less than water (below 100 celsius) with different heat sources such as waste heat, solar heat, geothermal heat...
Now I read sime articals about using propane gas which needs minus 42 degrees to start boiling...
Hi guys:
I have an idea of using hot water (the water temp is about 50 celsuis if not more coming from water well) to run ammonia-water refrigeation unit. however in most of the articals I read about such process it looks like the minimum evaporator temperature we can get with such system is...
Hi guys:
I was looking to find thermodynamic or aerodynamic section to put my threat in which is :
As i understand water cooling towers work on evaporation cooling principle, with the water temp drop depending on initial water temp and air initial temp and humidity or (wet bulb temp)!
now if...
