In a cyclic comprising of air compressor and expansion, workdone by a prism during the compression stroke is 9.2KJ and the heat rejected to the surrounding is 50KJ. During the expansion stroke workdone by air on the prism is 8.4KJ. a) Determine the quality of heat transferred to or from the system. Tullow oil has discovered a large volume of crude deposit at Cape-3-Point along the western coast of Ghana after years of intensive exploration. In the Company’s bid to start exploration, Green Ghana an environmental protection NGO took Tullow to court to prevent the Company from embarking on the said project citing numerous environmental concerns. b) As an energy and sustainability expert, what do you think are the side effects of the project and their remedies? A cooling water pump is operating at a speed of 1800rpm. Its flow rate is 1800L/minutes at a head of 14.4m and the power of the pump is 45kw. c) Determine the power required if the pump speed is increased to 3600rmp. (d)With the aid of a well-labeled diagram, discus two advantages and disadvantages of a closed system.
