Construct the network and find the critical path and project completion time.

Develop the Work Breakdown Structure (WBS) for a wastewater processing plant construction project. The WBS should contain three levels and at least 10 work packages. Use the spreadsheet approach and add a WBS dictionary.

Customers arrive at a ticket counter at a rate of 50 per hour and tickets are issued in the order of their arrival. The average time taken for issuing a ticket is 1 min. Assuming that customer arrivals form a Poisson process and service times are exponentially distributed, find the average waiting time in queue.

Energy and system size calculation TEQ assessment (4.1) Design a question to calculate the cooling load for the building you selected for You will define at least FOUR types of heat gain in that building (or the floor you are working on or you are familiar with). The indoor temperature is set as 75 F, and you can assume the outdoor temperature based on the location of your building in the summer and any other numbers needed to resolve this question. (4.2) Calculate the corresponding cooling load for the question you designed above. For all the details as well as the final answer that this question is asking for, clearly indicate the unit for each piece of information. In a word, you will design a question for your building about cooling load calculation. Assumptions and/or supporting drawings/figures/tables are allowed and encouraged. You can decide the level of detail for this question, e.g., the more details and the more accurate information, the more accurate and realistic your…

consider a crane with a 30 pound ball suspended from a 40 foot cable that weighs 5 pounds per foot.a) find the work required to wind up 15 feet of hte apparatus.b) find the work required to wind up all 40 feet of the apparatus.

A new type of energy absorber is being designed as a buffer at the end of track at a fairground.It consists of a piston with small holes that moves in a cylinder containing oil, so that the kineticenergy of impact is absorbed as heat by the oil.a) Draw a sketch for the instant of impact by a vehicle of mass 2500kg moving at 30mphshowing the forces and energy transfers involved.b) Write down the first law of thermodynamics for a system and identify terms that are notrelevant if the oil is taken as the system.c) How much heat transfer to the surroundings is required to return the oil to its originaltemperature after an impact by a 2500kg vehicle moving at 30mph?
