1.) Electric current flows through a flat steel plate that is 1 cm thick. Electrical power is dissipated via Joule heating of the plate. At steady state, the temperature distribution across the thickness of the plate is given by: TT(xx) = 2.5 K�1 − xx2 (0.5 cm)2� + 10 K � xx 0.5 cm� + 313 K The two surfaces of the plate are located at x = -0.5 cm and x = 0.5 cm.
The thermal conductivity of the plate is 50 W/m/K.
a. How much electric power is dissipated per unit area of the plate?
b. What are the values of heat flux at the two surfaces of the plate?
c. For each surface, is the heat flux directed toward or away from the surface?

answer:

in baseband transmission the whole bandwidth of the cable is utilized by a single signal. eg.Ethernet is using Basebands for LAN.

In the broadband transmission, multiple signals are sent on multiple frequencies simultaneously using a single channel. eg.Digital Subscriber Line (DSL)

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.
