A steady state economy is an economy (especially a national economy but possibly that of a city, a region, or the world) of stable size featuring a stable population and stable consumption that remain at or below carrying capacity. In the economic growth model of Robert Solow and Trevor Swan, the steady state occurs when gross investment in physical capital equals depreciation and the economy reaches economic equilibrium, which may occur during a period of growth. WebClass example 4. An open system at steady state receives steam from a first stream at 10 𝑏𝑎𝑟, 320°C and 2 𝑚/𝑠. A second stream enters the system at 30 𝑏𝑎𝑟, 400°C and 3 𝑚/𝑠. The cross-sectional areas of both inlet streams are 0 𝑚ଶ. a) Determine the mass flow rate at which the steam exits the system.
