Aspherical tank for storing liquid oxygen on the space shuttle is to be made from stainless steel of 0.80 m outer diameter and 5 mm wall thickness. the boiling point and latent heat of vaporization of liquid oxygen are 90 k and 213 kj/kg, respectively. the tank is to be installed in a large compartment whose temperature is to be maintained at 240 k. specify an appropriate insulation material and thickness of this material that will maintain oxygen losses due to boiling below 1kg/day assuming a combined convective and radiation heat transfer coefficient of 10 w/m2k.

answer:

yes that is right have a good day

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.
