To estimate losses from pipes (Qpl), the following equation can be used:
T = temperature of water flowing through the pipe (°C). (UA)p = heat loss-area product for the pipe (W/°C).
The equation can be used to estimate the losses from pipes between the storage tank and the heat exchanger or in the collector array by the use of appropriate temperature (T). For higher accuracy in long pipe runs, the pipe can be separated into small segments and the outlet temperature of one segment is the entering temperature to the next.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
