as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

The Use of Cooling Curves in the Determination of the Phase Diagram for a Lead-Tin System V.O.L.Tabell Department of Mining‚ Metallurgical and Materials Engineering University of the Philippines‚ Diliman vo_tabell@yahoo.com Abstract This paper discusses the use of the cooling curves in the determination of the phase diagram of a Lead-Tin system. The inflection points of these cooling curves were obtained by melting a series of mixtures of lead and tin at varying compositions. These critical

countries‚ a strong increase in the demand for building cooling and air-conditioning is detected and predicted for the following decades (by a factor of 4 in 2020). The reasons for this general increase are manifold‚ such as an increase in comfort habits‚ currently still low energy costs‚ architectural trends like an increased fraction of glazed areas in buildings and last but not least lowly changing climate conditions. This rising demand for cooling and air-conditioning in buildings involves unfavourable

Introduction: In industry‚ a heat exchanger is used to cool down streams for temperature sensitive processes. The now hot cooling water is useless to the plant unless something is done to cool it down. In industry‚ cooling water towers are used to bring the water back down to a sufficient level . In a cooling tower‚ outside atmospheric air is flowed through a “column” while the hot water sprayed into the system. Since air is never at full saturation of water (unless it is raining)‚ some of the hot

A Day of My Life in 2020 Today is May 28th‚ 2020. My name is Muhammad Sohail. I am an electrical engineer. I am working at Endeavours Energy as senior engineer. I usually get-up at 6 am to go to my office. First I go to my bathroom. My bathroom is about 30 square foot. In my bathroom i have air flushed toilet which highly water efficient. My air flush toilet uses 1.35 litres of water per flush compare to old toilet which uses 9.2 litres of water per flush. Back in 2011 these types of toilets were

rooms‚ and other clean room applications. TYPES OF COOLING SYSTEMS The most common air-cooling systems are either direct expansion (DX) type or the chilled water type. DIRECT EXPANSION (DX) SYSTEMS In DX systems‚ the air is cooled with direct exchange of heat with refrigerant passing through the tubes of the finned cooling coil. All these systems are comprised of a hermetically sealed or open compressor(s)‚ evaporator (cooling coil fabricated out of copper tubes and aluminum fins)
