1. Identify and visit a local facility that uses cold thermal storage. Conduct a forensic study to determine if the cold storage system is well-suited for the given application today. Consider costs, effectiveness in providing the desired cooling, contribution to global climate change, and other pertinent issues. If the cold storage system is well suited for the application, document that. If the cold storage system is not well suited, recommend system upgrades or an alternative approach for obtaining the desired cooling. Prepare a PowerPoint presentation of your findings.
2. A vertical, closed-loop geothermal heat pump is under consideration for a new 50,000-ft2 school building. The design capacity is 100 tons for both heating and cooling. The local water table is 150 ft, and the ground water temperature is 558F. Specify a ground source heat pump as well as the number and depth of wells for this application and develop a layout of vertical wells and piping required by the system.
3. Investigate the economic feasibility of using a waste heat-recovery heat pump for domestic water heating that employs ventilation air being discharged from a dwelling as the source. Assume typical hot water use of a family of four living in a 2200-ft2 single-family dwelling in your locale. Write a report of your findings.
Problem 1: A projectile is launched at point A with initial velocity 120 m/s and initial angle 40o as shown. In addition to the gravity, the wind exerts a horizontal acceleration of 2 m/s2 to the left on the projectile. Determine the flight time fo..
