room in a building has dimensions of 5.5 mx 4,5 m x 3.0 m. The room has two external walls and two external vindows of single clear glass. The area of each window is 2 m?. The overalI heat transfer coefficients for the walls, lass windows, and the ceiling are 2.0, 5.2, and 1.2 W/m K, respectively. The inside and outside design temperatures re 23 °C and -5 °C, respectively. Calculate the followings: a- The unheated mean radiant temperature. b- Explore the possibility of using underfloor heating system to heat the room. C- Minimum floor area needed for the underfloor heating system. d- Water flow rate. e- pump head required for underfloor heating system. Make reasonable assumption concerning the number of pipe loops and pipe diameter.

Help me please
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
Simple Machines-Levers, Inclined Planes, and Pulleys Directions: Use the appropriate equation to answer the following questions. All answers should be recorded below or in your Engineering Design journal. Remember to show all work. A lever has an effort arm that is 5 meters long and a resistance (load) arm that is 3.5 meters long. How much effort is needed to lift a 100 Newton weight? 5K i). Draw the figure representing the problem ii). How much effort is needed to lift a 100 Newton weight? iii). What is the Actual Mechanical Advantage 1. 5m i) AOON 5-5m

1. “The grain size of metal sheet influences its formability in two opposing ways. The yield strength of a metal increases as the grain size decreases. So, the formability of a component may decrease if the grain size gets too small. Larger grained metals have better formability, but the roughened surface that results from stretching metal with grain sizes that are too large is unacceptable for many applications. During a recrystallization anneal new grains form in the metal. The final grain size depends on the annealing temperature and annealing time.” As shown in the figure below (1"x1" area under a 50Xmagnification microscope), a cold-rolled metal has been annealed at 550 degrees C for one hour. Calculate the ASTM Grain Size Number for the following condition: image attached

SHOW YOUR SOLUTIONS PLS, THANKS show me how you did it so I can understand, thank you. Pls answer both, this is my last tutor question, pls. thank you. (Porosity). A dry rock weighs 240 grams and has a bulk density of 2.4 grams per cubic centimeter. When saturated with pure water at room temperature (T=25°C), it weighs 250 grams. At room temperature, the specific volume of water is 1.00295 x10-3m3/kg. Calculate the porosity of the sample. (Permeability). A cylindrical core sample of 1 cm length and 1 cm2cross-section has upstream and downstream pressures of 2 atm and 1 atm, respectively, during steady state flow of water at 0.997 g/s at room temperature. Calculate the permeability of the core. Note: Water @ 25°C, viscosity = 1 cp, density of water = 0.997 g/cm3.
Topics: Statics of Rigid Bodies, Equilibrium of Rigid Bodies, Equilibrium in Two Dimensions, etc. I will rate you with “LIKE/UPVOTE," if it is COMPLETE STEP-BY-STEP SOLUTION. If it is INCOMPLETE SOLUTION and there are SHORTCUTS OF SOLUTION, I will rate you with “DISLIKE/DOWNVOTE.” THANK YOU FOR YOUR HELP. PS: If you have answered this already, don’t answer it again; give chance to other experts to answer it. I want to verify if all of you will arrive in the same final answer; thats why I ask it multiple times. If you answer it again, i'll dislike all your entries/answers.
