What's a dead and. and is it safe to use a proportional control with a solid-state relay

My group members and I are trying to build a snow heating mat. So far, we are using nichrome heating wires sandwiched in silicone rubber connected to an arduino that controls a solid state relay to turn on and off electric current from a wall plug. What I want to know is how to control the...

Yh it is, there are already solutions out there but they are all terribly confusing and I was just hoping someone on here would know of some sort of relationship between the UA (U being overall heat transfer coefficient and A being heat transfer area) product to inlet and outlet temperature...

I am trying to design a heat exchanger for a stratified hot water tank which means that the heat transfer on that side of the exchanger will be totally dependent on free convection. I plan on using a shell and tube set-up but I have no idea on how to calculate the required mass flow rate from...

I'm not sure if I'm supposed to post this here, if I'm not, I'm sorry. That being said, what kinds of rubber can be heated up to 30 degrees c without degradation but can be melted. I would like to sandwich a heating filament between two sheets of rubber and seal them together with heat.

Homework Statement I am trying to derive the formula for time varying thrust given that I know the initial mass/volume of water in a water rocket. Knowns will include initial pressure, initial volume of water, and nozzle cross sectional area. Homework Equations Bernoullis equation: (p/ρg) +...
