Transport Processes (SKKK 2313) ASSIGNMENT # 1 1. Consider a steam pipe of length L=20 m‚ inner radius r1=6 cm‚ outside radius r2=8 cm‚ and thermal conductivity k=20 W/m.k. The inner and outer surfaces of the pipe are maintained at average temperatures of T1=150oC and T2=60oC‚ respectively. Obtain a general relation for the temperature distribution inside the pipe under steady conditions‚ and determine the rate of heat loss from the steam through the pipe. Assume that heat transfer is one-dimensional

Environmental Policy There’s a Snake Eating my Dog! The environmental stepwise process is a process people take to implement‚ assess‚ and interpret environmental related policies. The first step is to identify the problem‚ this is rather simple because there are lots of problems in our day-day lives. Next you have to Pinpoint the roots of the problem‚ followed by envisioning a solution for these problems. Now‚ a particular issue could have multiple causes‚ and thus multiple solutions. The you

Anaerobic digestion Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide

Coastal areas can be protected from the effects of natural processes‚ for example the effects of erosion‚ deposition‚ transportation‚ weathering and mass movement. The most problematic of these is erosion. There are three types of erosion: hydraulic action‚ abrasion and attrition which all contribute together to erode cliffs‚ causing the coastline to be vulnerable and weaker. The cause of erosion can then lead to mass movement for example rock fall and slumping which can affect the coastline greatly

Industrial Chemical Processes Essay Tan Hung Kai Grade 11 In our present world‚ there are thousands of chemical processes that are being used to produce products that benefits our daily lives. Industrial Chemical processes are used for “transforming raw materials into useful commercial products for society”. (Dr. Philip Britz-Mckibbin Industrial Chemistry: CHEM 2013) Examples of industrial chemical processes include distillation‚ smelting‚ disinfection‚ and Pyro processing. Even today‚ scientists

Dear local council‚ After undertaking my investigation in the effectiveness of current coastal management strategies at Collaroy Beach and Long Reef I have come to a few conclusions which will sustain the beach for many years to come. Whilst acknowledging the strategies in place‚ I graded their effectiveness and considered the human and environmental impacts. I investigated the issue concerning coastal erosion by doing some firsthand work at Collaroy Beach and Long Reef and by some secondary research

Cognitive Processes Paper Maggie Morrison PSY/560 December 3‚ 2013 Isabelle Three types of cognitive processes Subliminal perception is believed to be effected by its based finding of mind control‚ weather it’s one person or group of people. Mind control can be used on a group of people without their awareness. The perception of this idea is to get people to do things that would not normally do. For instance‚ during the 1950s there was a message that says Drink

Strategic Management Processes Strategic management is a combination of three main processes which are as follows: Strategy formulation Performing a situation analysis‚ self-evaluation and competitor analysis: both internal and external; both micro-environmental and macro-environmental. Concurrent with this assessment‚ objectives are set. These objectives should be parallel to a timeline; some are in the short-term and others on the long-term. This involves crafting vision statements (long term

IMPACTS OF CLIMATE CHANGE ON COASTAL AGRICULTURE OF BANGLADESH Introduction Climate change (CC) is the most alarming issue facing the world today. The consequences of climate variability and climate change are potentially more significant for the poor in developing countries .The impact of climate change on agriculture will be huge and substantive. Coastal people are highly exposed to a range of natural hazards‚ from storms and cyclones to widespread flooding and coastal erosion. Table: Potential

Explain how coastal flooding presents environmental‚ social‚ economic risks for the UK (10 marks) Coastal flooding occurs when normally dry‚ low-lying land is flooded by sea water. Coastal flooding is a serious threat to the UK. Many British cities are situated on or near the coast‚ on low-lying land‚ together with 40% of the UK’s manufacturing industry and sea level rise means that the UK are more at risk. Greater London and the Holderness coast are areas that are vulnerable to coastal flooding
