hi, I'm look for mathematical formulas on drying of textile by both radiation and natural convection. Can anyone provide me some revelent informations. thanks in advance. Tkian

quark & jproj, Thanks a lot! regards, tkian

Dear all, I presently doing some investigation on a 2 flow (upper & lower)solar air collector. Can anyone tell me how to find the convection heat transfer coefficients h for the surfaces in the flow channel. thanks in advance regards, tkian

hi, Does anybody know why the wind velocity is always higher before a heavy rain or storm comes. regards, Tkian

Greg Locock, I had used a 30mm x 30mm solar cell, hook up two wires from the cell to a 100ohm resister and parallel to a multimeter. I realised that the voltages that I got from the multimeter is pretty linear with the radiation data captured by a pryanometer. Could you advise me whether the...

hi, I have seen from a response indicting that by using a single solar cell, mounted it in the same orientation as the collector and measure its short circuit current, it is possible to have accurate measure of the insolation. I would be glad if anyone chould provide me a detail working...

hi, I would like advises on getting a recent solar radiation data on australia. regards, tkian
