2. A steady flow, steady state thermodynamic system receives 45 kg/min of a fluid at 207kPa and discharges it from point 24 m. above the entrance section at 1034 kPa. The fluid enters with a velocity of 36.6 m/s and leaves with a velocity of 12 m/s. During this process, there are supplied 7 kW of heat from an external source, and the increase in enthalpy is 3.6 kJ/kg. Determine the work in kW and in horsepower. Answers: 3.82 kW, 5.22 hp a. the change in Potential Energy in kW O 176.5 0.4483 O 0.1765 b. the change in Kinetic Energy in kW -448.335 -0.4483 O 0.4483 c. the work (Wsf) in kW 4.57 3.83 5.22 d. the work (Wsf) in horsepower 6.12 5.22 4.57

Directions: Answer the questions after each situation. 1. David Aquino, engineering director, started out the day uptight. His young child had the flu the night before, and he had been up all night to help. Upon arrival at his office, David had to make urgent phone calls to approve a two-week overtime work plan due to a plant fire the night before and to plan for a product committee meeting the next day to counter environmental concerns about a wastewater treatment plant. Then he spent 30 minutes reviewing the qualifications of new candidates and decided on one. He asked for salary information and wanted to examine the offer before it was sent. He asked for further justification for the budget requested by industrial engineering for a minicomputer. Without reading it, he approved the research proposal from material engineering. He rejected an invitation to speak at a regional meeting of the Philippine Society of Mechanical Engineers by giving an untrue reason. David made a note for the…
Hi, Could you please help with this question, if you need to take more credits then please feel free. showing working out if possible too please, Thank you
PROBLEM 1 For the engineering activity, current practical capacity is defined by the following requirements: 6,000 engineering hours for each product group that has been on the market or in development for 5 years or less, and 2,400 hours per product group of more than 5 years. Four product groups have less than 5 years' experience, and 10 product groups have more. There are 24 engineers, each paid a salary of P60,000. Each engineer can provide 2,000 hours of service per year. The actual engineering usage was 46,000 hours. The standard is 58% of current practical activity capacity. Case 1: Calculate the (1) activity volume and (2) unused capacity variances for the engineering activity Case 2: Suppose the operational managers have selected some improvement measures that promise to reduce non-value-added activity usage by 40% in the following year. Using the targeted reduction, establish kaizen standards for engineering, expressed both in physical and financial measures

Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…

Summary/Conclusion Discuss the strengths of your design and how it met the specifications. Discuss your assumptions and why they are valid. Discuss what you might change about your design in a redesign effort. Format: The project should be presented as a design report using a word processor. Include any hand calculations in an appendix. More details will be provided. Choose to design either a slip-jaw or channel-lock pliers to last for 25 years of use by a professional. Use an appropriate tool steel for the pliers. Design for 95% male grip force. Use a minimum factory of safety of 2.50. Determine dimensions not given. Slip Jaw Pliers A= 9.00 inches B=1.00 inches C= ? D=1.25 inches H= 1.875 Inches D B A
