Ahollow sphere is constructed of pure aluminum with an inner diameter of 4 cm and an outer diameter of 8 cm. the sphere is covered with a 1-cm layer of insulating material having k = 50 w/m · k and the outside of the insulation exposed to h = 20 w/m2.k and t = 10c. the inside temperature of the sphere is maintained at 100c. (a) sketch the thermal resistance network and (b) determine the heat loss to the ambient.

answer:

sure that would be nice

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.
