These data are combined for all the streams in the plant to give composite curves, one for all hot streams (releasing heat) and one for all cold streams (requiring heat). The point of closest approach between the hot and cold composite curves is the pinch point (or just pinch) with a hot stream pinch temperature and a cold stream pinch ...
The source and sink composite curves is a graphical tool for setting water recovery targets as well as for design of water recovery networks. [5] A 2018 study found by water pinch and water footprint analysis that for bricks with typical materials of clay and shale, the water consumption footprint was 2.02 L of water per brick. [6]
5-million-year history, representing the Lisiecki and Raymo (2005) LR04 Benthic Stack Sections of sedimentary cores from off Greenland. Marine isotope stages (MIS), marine oxygen-isotope stages, or oxygen isotope stages (OIS), are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data derived from deep sea core samples.
The grand canonical partition function applies to a grand canonical ensemble, in which the system can exchange both heat and particles with the environment, at fixed temperature, volume, and chemical potential. Other types of partition functions can be defined for different circumstances; see partition function (mathematics) for generalizations.
A schematic showing equivalent sites, occupied (blue) and unoccupied (red), clarifying the basic assumptions used in the model. The adsorption sites (heavy dots) are equivalent and can have unit occupancy.
A diagram illustrating great-circle distance (drawn in red) between two points on a sphere, P and Q. Two antipodal points, u and v are also shown.. The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them.
The Nasdaq Composite is an often-cited stock market index — along with the S&P 500 and the Dow Jones Industrial Average — known for its large number of technology-related companies. Here’s ...
Consider a curve in a manifold ¯, parametrized by arclength, with unit tangent vector = /.Its curvature is the norm of the covariant derivative of : = ‖ / ‖.If lies on , the geodesic curvature is the norm of the projection of the covariant derivative / on the tangent space to the submanifold.
