Study of heat transfer in Shell and Tube heat exchanger. Introduction: Heat Exchanger is device that facilitates heat exchange between two or more fluids. They are used wherever efficient heat energy transfer is required particularly petrochemical plants‚ petroleum refinery‚ natural gas processing‚ air conditioners and refrigerators‚ sewage treatment etc. Considering wide spectrum it swaps ‚ the device is a necessity in most of the industrial applications. Categorization: Broadly Heat Exchanger

Installing a tank-type water heaters will not taking away the usable area‚ but also increasing your utilities Instead of heating the water 24 hours‚ tankless water heaters generate hot water when you need to use it‚ and that can help minimize the utilities bills‚ as well as the environmental impact. Tankless systems are using natural gas‚ propane or electric to operate the system‚ and the system will generate heat by using an extremely powerful heat exchanger. The

important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling. COOLING TOWER TYPES: Cooling towers fall

CRITICALLY EVALUATE THE FACTORS INFLUENCING THE GLOBAL HEAT BUDGET - 40 MARKS The global heat budget is the balance between incoming insolation‚ and outgoing radiation from Earth. There are many factors that influence this heat budget‚ some of which are more important than others. In this essay I am going to describe and explain each factor involved. Insolation is the incoming energy from the sun in shortwave ultraviolet (UV) radiation. The distribution of insolation over the Earth’s surface

low temperature and low pressure while condensation occurs at a high temperature and high pressure. Thus‚ it is possible to transfer heat from an area of low temperature (i.e.‚ water storage tank) to an area of high temperature (i.e.‚ environment). Regarding to the fig 3.1‚ beginning the cycle at the evaporator inlet (1)‚ the low-pressure liquid expands‚ absorbs heat‚ and evaporates‚ changing to a low-pressure gas at the evaporator outlet (2).The compressor (4) pumps this gas from the evaporator through
