A wing has a lift-curve slope of 5.2 per radian, and the product of eAR is 8. Given that a second wing has an effective aspect ratio (eAR) of 6.0 and the same airfoil as the first wing, how fast must this second wing travel in order to lift 3000 lbs. when it is at an angle of attack of 6.0 degrees. The area of the second wing is 300 ft2, and the angle of zero lift angle is -1.0 degree. Assume that both wings are operating at standard sea-level conditions.

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.
