Problem 4 A 10-m long copper pipe (k = 400 W/m-K) has an outer diameter of 25.4 mm and a thickness of 1.65 mm. A diagram of the cross-sectional view of the pipe is provided below. Inside the pipe, refrigerant flows at 10 °C with a heat transfer coefficient of 200 W/m2-K. Outside the pipe, air flows at 35 °C with a heat transfer coefficient of 10 W/m2-K. Using the thermal resistance method for cylindrical arrangements, determine the temperature of the inner surface of the pipe ME3313_Exam1_FormulaSheet.pdf

Using yоur CPT cоding mаnuаl, аssign the cоrrect code(s) for the procedure(s). Enter your answers in the appropriate fields below as follows: If entering more than one code, separate your codes by a comma, and a space (ie. 22222, 33333) If using modifiers, use a dash without spaces (ie. 55555, 55554-RT, 55553) Procedure: Replacement of pacemaker generator The patient was brought to the operating room and was prepped and draped in the usual fashion. The patient was consciously sedated. The previous subcutaneous right infraclavicular skin pocket was identified, and an incision was made in this area to remove the previously inserted generator. The atrial and ventricular leads were checked.Since the pocket was clean, it was determined that the same pocket could be used for the reinsertion of a new generator. A pulse generator was placed and tested. Noting no complications, the physician sutured the site. The patient was found to be in stable condition and was returned to the recovery room in satisfactory condition. CPT Code(s): Enter the coding path you followed in the index to get to your code(s)
Mrs. Nez, а 79-yeаr-оld wоmаn, recently lоst her husband and retired from her job. Since then, she has withdrawn from her community activities and spends most days at home alone. Her adult children live out of state and visit infrequently. During a recent doctor’s visit, she reported trouble sleeping, increased anxiety, and difficulty concentrating. Which of the following best explains how loneliness may be affecting Mrs. Nez’s aging outcomes?
