Problem 2 A 4 mm diameter and 20 cm long aluminum fin (k 240 W/m-K) is attached to a surface. If the heat transfer coefficient is 12 W/m2 K, determine the percent error in the rate of heat transfer from the fin when the infiniely long fin assumption is used nstead of the adiabatic fin tip assumption.

Analyzing a Fin Consider an infinitely long fin with a square cross section with 5mm. The base of the fin is held at a fixed temperature of To = 100°C and air is passing by the fin at T = 20°C with a convective heat transfer coefficient of h - 55 W/m-K. The fin is made from aluminum with a thermal conductivity of k- 180 W/mK. T. = 20°C n...

4. An exothermic material is encased in a 1-m-long thin tubular sleeve. The material generates heat at a steady rate of 4800 W/m. The thermal conductivity of the exothermic material is 22 W/mK. The radius of the tube is 30 cm, and you can neglect the thickness of the sleeve. Also assume the ends of the tube are perfectly insulated. (a) If the tube is exposed to air at 20°C, and if the convection coefficient between air and the tube...

4) The lifetime in hours) of a certain type of light bulb is approximately normal with a mean of 1,000 hours and a standard deviation of 70 hours. What is the probability that the bulb will last between 1050 and 1150 hours? Assume normal distribution. Solve the problem in two (2) completely different ways * 1 way using normal table and 1 way NOT using normal table. (9 marks)

Heat capacity can be defined in two ways: 27.) ДТ )v-const. AT P=const. Use conservation of energy and the equipartition theorem to calculate expressions for both of these for solids, monatomic gases, and diatomic gases. Use the table of Cp values, provided, to check that you ca approximately, account for most of these.

Q2. (5 pts) The estimates for two machines, X and Y, are given in different ways in a company as shown below: Machine X in constant-value (today's) dollars while Machine Y in future (then-current) dollars. The company's MARR is equal to the real rate of return of 10% per year, and inflation is 3% per year. Use PW analysis to determine which machine is better. You can use the below factor formula in case the factors table is not available....
