Write a detailed report to a technical manager on the following items. You work as field engineer at Menco Company and dealing with repair of Getinge autoclaves. You recently attended to three autoclaves at Uro Hospital. The first and second autoclave had error of liquid cycle activated while running, you bypassed the door emergency switch and its functional but need replacement of faulty spares. The third had vaccum pump failure, faulty vaccum pump. The report to be detailed and fit two A4 pages.

If Indiana County, Pennsylvania, coal with M = 3% and A = 8.5% is burned with 10% excess air, calculate the actual air fuel ratio and the ideal Orsat analysis (no CO and no unburned carbon). Also, determine the theoretical Orsat analysis if the HHV of the refuse is 5500 kJ/kg and the % CO in the dry flue gas is 0.2% of the dry flue gas.

Q1- Why has the enormous potential of shale gas, as a viable fuel source, only recently (10-15 years ago) received serious attention?

What are the various sensors used in hybrid vehicles and Detailed explanation of the same

Q1- Explain how industry uses natural gas (cite a specific industry example)?

Q2- Why is natural gas projected to become increasingly popular as a prime fuel source, compared with coal, for electricity generation?

ASSIGNMENT WEEK 1 (Metal Casting)

1. Name the two basic categories of casting processes. (CO1,C2)


2. What properties determine the quality of a sand mold for sand casting?


3. What is the difference between vacuum permanent-mold casting and vacuum molding?


4. What are the most common metals used in die casting?

5. Which die-casting machines usually have a higher production rate, cold-chamber or hotchamber, and why?


6. What is flash in die casting?


7. What are some of the operations required in sand casting after the casting is removed from the mold?


8. What are some of the general defects encountered in casting processes? Name and briefly describe three.

Hydrogen at 25oC and 0.1 Mpa is fed to the head of a cutting torch. Calculate the adiabatic flame temperature if the hydrogen is burned with 256% excess air at at 25oC and 0.1 Mpa,

a) without taking into account dissociation

b) assuming equilibrium composition of water has been achieved (both dissociation reactions of water reach chemical equilibrium)

Consider the topic: Identifying the causes, challenges and solutions of fishing vessel engine failure in Ghana?

In writing please take note of the following: The topic is not about fishing. Its about fishing vessel engine failure. So first explain what a fishing vessel is, sating types, origins, and how they are used. Then you talk about engines of vessels and their brands/types. Explain what an engine failure means and the various possible causes of engine failures. What happens when vessel engine fails from the past scenarios and how such cases were dealt with, etc etc

Describe two different designs utilized for separation of water and gas for oilfield applications.

Saturated steam condenses at the surface of a 200 mm pipe with the length of 2 m and temperature of 90 C. Find the rate of heat transfer and total condensation rate if the pressure is atmospheric. B)The bottom of a copper pan, 100 mm in diameter, is maintained at 109°C by the heating element of an electric range. Estimate the power required to boil the water in this pan. Determine the evaporation rate. What is the ratio of the surface heat flux to the critical heat flux? What pan temperature is required to achieve the critical heat flux?

Assume that Stage 1 (home market) of the business produced 200 vehicles using a craft manufacturing approach. Discuss how your manufacturing approach might or might not be different for Stage 2 (international market). In your discussion, consider and contrast craft production, mass production and lean manufacturing. Identify and discuss at least two approaches using lean principles.

A. Identify, discuss and analyse the project management techniques and software such as Trello, Slack, meeting minutes that your group used in this unit. Consider, which aspects worked well and which did not; and how you could improve the management of a similar project in the future.

You have recently been employed by DRYSON, a start-up in the business of manufacturing and supplying home appliances through online stores. DRYSON’s business model is based on evaluating and understanding existing successful products, then improving on their design. You have been assigned to advise DRYSON on the design of a new top of the range hand-held hair dryer.

A hair dryer is a hand-held device that accelerates the hair drying process by blowing out high velocity hot air.

a) Identify the primary function of the hair dryer. Develop a functional tree diagram (fast diagram).

b) Identify and group the stakeholders. Propose and discuss strategies for identifying the customer needs.

c) Propose a performance requirement relating to each of the following: airflow, surface temperature and exit air temperature (three requirements in total). Identify verification categories and methods for each of those requirements – justify your choice. Ensure that you use appropriate requirement terminology.
