A empresa de tecnologia anunciou um novo smartphone com câmera aprimorada, tela maior e bateria de longa duração por um preço acessível. O dispositivo tem como objetivo atrair mais consumidores em mercados emergentes com suas especificações equilibradas e preço baixo. Analistas esperam que as melhorias e o preço baixo impulsionem as vendas do novo aparelho.
This document describes the main parts of a plant: roots anchor the plant and absorb water and nutrients from the soil, a stem supports the plant and transports water and nutrients between the roots and other parts, and leaves use sunlight to photosynthesize and produce food for the plant. Flowers produce fruits which contain seeds for reproduction.
This document introduces Grape, an open-source Ruby framework for building REST-style web APIs. It discusses how to install Grape, create CRUD actions, add namespaces and versioning, validate parameters, add authentication, and support different API formats. It also compares the performance of Grape to Rails APIs, finding that Grape has a higher request throughput and lower latency. Resources for learning more about Grape include its Google Group, YARD documentation, and wiki.
The document discusses flowmetering steam. It begins by quoting Lord Kelvin about the importance of measurement. Many businesses now recognize the value of energy cost accounting, conservation, and monitoring techniques using tools like flowmetering. Steam is difficult to measure accurately. Flowmeters designed for liquids and gases don't always work well for steam. The document then discusses fundamentals of fluid mechanics including density, viscosity, Reynolds number, and flow regimes as they relate to measuring steam flow. Accurately measuring steam use allows optimizing plant efficiency and energy efficiency through monitoring steam demand and identifying major steam users.
Steam is a widely used and efficient energy carrier that can be generated and distributed economically via centralized boiler plants. It can transfer large amounts of energy over long distances through relatively small diameter piping without needing pumps. Steam systems are flexible and easy to control by adjusting pressure. Modern steam systems are automated and efficient, providing energy for many industries and applications.
This document discusses various methods for reducing steam pressure, including self-acting direct operating valves, pilot operated valves, pneumatic controls, electropneumatic controls, and electric controls. It provides diagrams to illustrate common pressure reducing station configurations, such as direct acting, pilot operated, pneumatic, electropneumatic, electric, parallel, and series arrangements. The advantages and disadvantages as well as typical applications are outlined for each pressure control method.
