Heat Transfer: A Practical Approach
... A 3-m diameter spherical tank filled with liquid nitrogen at 1 atm and -196°C is exposed to convection and radiation with the surrounding air and surfaces. The rate of evaporation of liquid nitrogen in the tank as a result of the heat gain from the surroundings for the cases of no insulation, 5-cm t ...

... Since h = u + Pv and, for an ideal gas, Pv = RT, then for the ideal gas h = u + RT R is constant, and u = u(T) only, so we conclude h = h(T) only for an ideal gas. Aside: application of enthalpy balance in steady-flow system: energy balance for a single-stream, steady-flow system with negligible ch ...

THE FIRST LAW of THERMODYNAMICS: Conservation of energy
... To obey the First Law (du=dw), T must increase. In contrast, T remains constant during the isothermal compression. Since the final temperature is higher in the adiabatic compression, therefore (by Ideal Gas Law), final P must also be higher than for isothermal process: So adiabat is steeper than iso ...

Insulated glazing
Insulated glazing (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane) is double or triple glass window panes separated by a vacuum or other gas filled space to reduce heat transfer across a part of the building envelope.Insulated glass units are manufactured with glass in range of thickness from 3 mm to 10 mm (1/8"" to 3/8"") or more in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are manufactured with the same thickness of glass used on both panes but special applications such as acoustic attenuation or security may require wide ranges of thicknesses to be incorporated in the same unit.
