11 Heat and Material Balance - Chemistry, Software

Heat balance calculations are usually carried out when developing new chemical processes and improving old ones, because no process can work if too much heat is released or if there is a lack of thermal energy to maintain the reaction temperature.

Earth's energy budget - Wikipedia

Earth's energy budget accounts for the balance between the energy Earth receives from the Sun, and the energy the Earth radiates back into outer space after having been distributed throughout the five components of Earth's climate system and having thus powered Earth's so-called heat engine. This system is made up of Earth's water, ice, atmosphere, rocky crust, and all living things.

Heat and Mass Balance - EnggCyclopedia

Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.

Temperature-heat (T-Q) diagram The T-Q diagram is a useful tool for designing heat exchangers. It can also be used to present the heat transfer characteristics of an existing heat exchanger or heat exchanger network. The T-Q diagram consists of two axes: The current stream temperature on the y-axis and the amount of heat transferred on the x-axis.
