Avery effective low-temperature insulation is made by evacuating the space between parallel metal sheets. convection is eliminated, conduction occurs only at spacers, and radiation is responsible for what little heat transfer occurs. calculate q between 150 k and 100 k for three cases: (a) two sheets of highly polished aluminum.(b) three sheets of highly polished aluminum. (c) three sheets of rolled sheet steel.

answer:

person b

explanation:

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
