    convective flow

    well in that case i'm sorry that i asked the question in the first place. although, i really don't see where the big hang up is - i'd really rather have that explained to me rather telling me that i'm living in some kind of lala land. That is completely unhelpful. cold water falls, pushes...

    convective flow

    I tend to disagree. You can remove 7% of a nuclear reactors power output through natural circulation and that is without an obscene difference in height. Granted you are not using mechanical energy to spin a turbine. But, that is more an issue of designing the system to minimize head loss and...

    convective flow

    perfect. Thanks a bunch. BTW, I'm assuming that there is a general design guideline for sizing pipes vs. volumetric flow rate. In my scenario, I want to minimize head loss so, I would want to oversize everything to the extent practical from a cost standpoint as to minimize non-useful energy...

    convective flow

    So, How would the difference in height affect the differential pressure? density is usually in kg/m^3 or lb/ft^3 pressure is psi or metric equivalent so, if the cold leg is something like 980 kg/m^3 and is at 25ft in the air and the hot leg is 900 kg/m^3 and is at 0 ft relative elevation...

    convective flow

    I don't believe there are any commercial solar panels out there that are designed to do what i want to do. Basically the issue with solar panels is that they are only 10 to 15 percent efficient. Whereas a water turbine is upwards of 70 percent and as long as i can minimize heat loss through...

    convective flow

    the other thing that i'm noticing while reading through this is that the focus is primarily on heat transfer. In my applicatioon, i really do not care about that. What i care about is the fluid flow, in gallons per minute, based upon an experimentally determined rate of heat input. i.e. if i...

    convective flow

    Basically what i want is something that i can just plug and chug into. I want to essentially have water/ethylene glycol mixture 30 ft x 10ft x .25 inch solar panel. I want to have a 25 or 30 ft high vertical pipe connected to it, where it would flow upwards into a heat exchanger and then...

    convective flow

    hey, thank you very much! When I was clicking the link, i thought for sure i was going to some place where i could purchase the appropriate text - i was super excited when i saw that i could just download the thing! Awesome help! I'll be back though if i need some clarification! Wes

    convective flow

    Hi, I'm working on designing a natural circulation system. I'm hoping for some help. I need some help determining flow rate based upon differential temperature and also calculating what pressures will exist at various points in the system. Thanks a ton Wes
