    correlation for subcooled boiling

    Sub cooling and super heating are states beyond the saturation point. sub cooling being any temp below saturation and super heat being any temp above saturation. While things boil they do not change temp or pressure. A liquid with any percentage boiling will not change temp. The temp can...

    How to add additional cooling to motor

    Is this an old motor? 90% of electric motor failure is due improper lubrication. If dirt gets inside the windings it will cause hot spots and make the motor over heat. This may be more of an issue if the ambient is high. Taking the motor apart and cleaning it may help.

    Please define "small temperature" in regard to HVAC

    Yes the approach is always the temp of the fluid transferring energy. If the refrigerant is 40 you never reach 40. In this case I think small temp is the difference between the inlet and outlet of the fluid being cooled. Less difference (small) less heat transfer. Anything coating the inside...

    Please define "small temperature" in regard to HVAC

    The greater the temperature differance the better the heat exchange. The smaller the differance the less work that is being done. One 1/16th of an inch of scale on the inside of the tubes can reduce efficiency by as much as 20%. When was the last time you sprayed the condesing coil off in...

    Air Conditioner Question

    Yes the heat of compression needs to be rejected outside. This is usually 17,000 BTU's per ton of cooling (12,000 BTU's). However scroll compressors are more efficient then recips so this number may go down. Also the condensers are now oversized (the outside part) this allows for greater heat...

    fluid dynamic modeling

    Thanks David, I am not aware of any condensing turbines that can condense more than 8% during energy coversion, this of course is only my limited knowledge of the field. This turbine can run on any pressurized fluid (combustion gas, steam, refrigerant, air, water). The theortical part is that...

    fluid dynamic modeling

    I have invented a new type of turbine. This device will convert energy while the working fluid condenses. There are no models for this type of fluid flow, so I am told. With out this information it will be hard to get the most efficient design. Is there anyone working on this type of...
