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.

Draw the functional tree diagram of a hair dryer using its primary function and sub-functions.

A 140litre container is to be used to store heat for a domestic heating system. There are two options for the storage material, lead blocks or clay bricks. Using the data provided determine which is the best option for the system.                                                         

Lead: specific heat 130J/kgK, density 11340kg/m³

Brick: specific heat 840kJ/kgK, density 2000kg/m³

2. A container holds 0.25m³ of compressed air at 900kPa and 20°C. This is expanded polytropically via a process with n=1.3 to a pressure of 150kPa. Determine;         

(2 marks each)

1. The mass of air
2. The final air temperature
3. The work transfer, stating if it is input or output work
4. The change in internal energy
5. The heat transfer , stating if this is heat input or output

please answer both the questions/

Consider a regenerative vapor power cycle with two feedwater heaters, a closed one and an open one, and reheat. Steam enters the first turbine stage at 12 MPa, 560 °C, and expands to 1.5 MPa. Some steam is extracted at 1.5 MPa and fed to the closed feedwater heater. The remainder is reheated at 1.5 MPa to 440 °C and then expands through the second-stage turbine to 0.3 MPa, where an additional amount is extracted and fed into the open feedwater heater operating at 0.3 MPa. The steam expanding through the third-stage turbine exits at the condenser pressure of 10 kPa. Feedwater leaves the closed heater at 220 °C, 10 MPa, and condensate exiting as saturated liquid at 1.5 MPa is trapped into the open feedwater heater. Saturated liquid at 0.3 MPa leaves the open feedwater heater. Assume all pumps and turbine stages operate isentropically. Determine for the cycle:
      a) The rate of heat transfer to the working fluid passing through the steam generator, in kJ per kg of steam entering the first-stage turbine.
      b) The thermal efficiency.
      c) The rate of heat transfer from the working fluid passing through the condenser to the cooling water, in kJ per kg of steam entering the first-stage turbine.

1. (a) The air conditioning unit of a car is operating on a summer day when the temperature is 37°C. It cools the air to 6°C using 3kW of power output. The A/C has a COP of 4. Find the mass flow rate of the cold air that the A/C unit can provide on that particular day. (15 points)

2. (b) A building freezer that is used to freeze vegetables requires 40 tons of refrigeration to keep the food frozen. The temperature of the freezer is -35°C and the ambient temperature outside the building is 30°C. If the performance of the freezer is 20% of the theoretical best possible cycle, what is the power required to run the freezer. 1 ton of refrigeration is equivalent to 210 kJ/min. (15 points
