I'm looking for a material that has a similar thermal conductivity to granite but is more cost effective to use than granite itself. A materials scientist recommended mortar because of this factor. Does concrete have a similar thermal conductivity to granite too? I wouldn't imagine it would be...
I have a bluetooth device that is setup to transmit data to my phone, and I am planning to use it in building a temperature sensing device in the ocean. Will this device be able to transmit a bluetooth signal through a space with the following dimensions (lxwxh): (13.5x5.0x1.5cm) to another...
I'm looking to build a temperature sensing instrument that sits atop a mortar platform in between high and low tide on the ocean. This block of mortar will be regularly prone to wave energy and must be able to withstand constant wave forces up to ~100psi. It also must be fairly resistant to...
