PVC pipe thickness varies widely depending on its size and application. Generally, PVC pipes are categorized into schedules which denote wall thickness. The most common schedules are 40 and 80, with Schedule 40 being thinner and thus less pressurized compared to Schedule 80. For instance, a 1-inch Schedule 40 PVC pipe has a wall thickness of 0.133 inches, while a Schedule 80 of the same diameter has a thicker wall of 0.179 inches. This difference allows Schedule 80 pipes to handle higher pressures. It's essential to select the proper schedule based on the requirements of the system - whether for household use, industrial applications, or irrigation, ensuring safety and efficiency.

The material property of carrier mobility plays a significant role in determining electrical conductivity. and this is also true for titanium dioxide TiO2. Its carrier mobility is heavily influenced by factors such as morphology. crystal structure rutile. anatase. and plagioclase. mixing. and temperature. As a result. the carrier mobility of TiO2 is generally low. This characteristic makes it a popular semiconductor material in photocatalysts and solar cells. Numerous experimental studies have demonstrated that the electron mobility of TiO2 rutile phase falls within the range of 0.1-1 cm^2/Vs. while hole mobility is much lower at around 0.001 cm^2/Vs. However. these values can be enhanced through methods like doping or altering the nanostructure of TiO2. It's worth noting that these values are approximate and may vary depending on various factors like temperature. crystal quality. defects. etc.

The surface of titanium is protected by titanium dioxide. which prevents corrosion. However. corrosion can occur under certain extreme conditions.
