Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…

Hello Sir.Good Evening. I have a question in my home work related Engineering drawings lesson. The following below is my question. Please advice thank you.

Match the following statements with the term that best describes each statement. hooks law creep impact strength proportional limit fatigue elastic

Q1: Select the correct answer. up to A. Resilience is the energy absorbed by the material a. yield. b. ultimate sensile stress. c. fracture. B. The grain boundaries are a. less chemically active than grains themselves. b. the regions of orientation mismatch of the neighbouring grains. c. classified as linear defects. C. All polycrystalline materials are considered as isotropic because a) they have crystallographic direction-mechanical properties independence relation b) all the crystals' orientations are the same c) the random direction of many grains cancels the anisotropic effect D. Dislocations slip process in metallic crystalline materials a) is essential to explain why the metals exhibit much lower strength than that theoretically predicted based on metallic bonding. b) makes metals and alloys brittle. c) cannot be used to control the mechanical properties of metallic materials E. The atomic stacking ABCABCABC is for d) FCC crystal structure e) BCC crystal structure f) HCP crystal…

I need help with the second table. and these questions   1- If 1 gallon of oil = 1.4 therm, how many gallons have been wasted by heat loss in Feb? (1 therm = 100,000 BTU)   2- If $1.30 per therm, how much did you waste from house heat loss in Feb?

https://www.sciencedirect.com/science/article/abs/pii/S0965997822001569 In the literature review, they should present the system installed and the main results obtained. In other words, the enhancement due to the installed system. They have to define the system used in this study. (the report talking about ventilation) pls in briefly Don’t using chatgpt please urgent i will give u good feedback

Procedure: 1. Copy the following table on a separate sheet of paper. 2. List all knowns 3. List all unknowns 4. List all equations that you need to use 5. Draw a diagram of the problem 6. Substitute and solve the problem. Be sure to show your work (1pt). 7. Final Answer 8. Take a picture and upload your answer! Problem: A 25 ft long solid steel rod is subjected to a load of 10,000 lb. This load causes the rod to stretch 0.477 in. The modulus of elasticity of the steel is 30,000,000 psi. Determine the diameter of the rod. (precision of 0.00) Table: #1 Substitute and Solve: Knowns: Draw: Unknowns: Equation: Final Solution
