Perhaps someone here can point me in the right direction here.
I design electrical heating elements, and a customer has asked me if I can design an element for dual voltage use. The easy answer for this is yes as he is asking for 380V 3ph and 220V 3ph. Its fairly simple to change the...
I am looking for input into what is the best/preffered method of soldering a nichrome resistance wire (18awg-30awg) to 18ga lead wire.
Currently we use a silver solder with a boron modified solder paste. For heat we use a small oxy-acet flame torch.
The nichrome is a resistance heating...
I have what I hope is a fairly simple question:
Should a condesate line be larger then the supply line?
I am not familiar with steam and boilers, I was told by a customer that the condesate line should be smaller then the supply line, and am curious as to hear other opinions.
I have been for some time trying to muddle my way through some heat transfer calculations. I would like to know if I should be considering convection in my thinking and if pressure would play a role.
My application uses an element on one side of an aluminum platen .625in thick with a surface...
