U-factor measures how well a product prevents heat from escaping a home or building (thermal conductivity). U-factor ratings generally fall between 0.15 and 1.20. (See more at: http://www.nfrc.org/windowratings/Energy- ratings.html#sthash.EUkrrint dpuf) A lower U-factor means a better-insulating window. The more common term R-value refers to the resistance of the window to heat conduction, and it is the inverse of the U- factor (that is, R-value = 1/U-factor). Better windows have high R-values and low U-factors. Determine all surface type of areas in Table 8-1 from the house in figure 1 and calculate R-values with the given U-factor Table 8 -1 Surface Type Size of area U-factor R-values (width x height = ff') a) Walls 0.06 b) Ceiling (**Assume the ceiling area is the same as rectangular floor area, A=L x W) 0.025 c) Total window x 8 ea (argon-filled, double glazed for all windows) 0.35 d) Total door (insulated steel entry doors) x 2ea 0.20

A technician uses these items in fixing a hot water heating system:Find the total cost of the items used.Note: Use this information and diagram for problems 21 and 22. TheR value of a substance gives the resistance of a substance to heatflow. The larger the R value, the more resistant the substance is toheat flow and heat loss. The total resistance is the sum of each substance’s resistance.

Question 20 of 20 < A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)? (a) Number i (b) Number i Units Units UNITS CHOICES: no units, degrees, s,…

Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…
