Assuming the house starts at 70 deg F and the outside temperature is 0 def F. (The heat has been turned off) can you determine the equivalent R rating? What if the outside temperature was 30 def F, then the rate of heat loss would be less. Can you recommend a reference
Questions About 90 Deg
A house is built on the top of a hill with a nearby 45 deg slope An engineering study indicates that the?
A house is built on top of a hill with a nearby 45 deg slope. An engineering study indicates that the slope angle should be reduced because the top layers of soil along the slope might slip past the lower layers. If the static coefficient of friction between two such layers is 0.5, what is the least angle through which the present slope should be reduced to prevent slippage?
I would like to use any Polymeric material as a Replacement for EN8 Shaft rotating around 110 deg. celcius.
when the outside temp is -40 deg celcius why the air craft window and shutter was terrible hot at west?
at west side window of jet airlines flight at seat # 24Fat 3pm , window and shutter was terribly hot,and radiating the heat unbearably through out the journey from delhi to chennai, even at 40000 feet at -40 deg celcius temp out side. what is the reason for this?
I am simply amazed you stupid little libtards are really this stupid. If they can't convict on the 2nd deg murder charge, Zimmerman walks.
Is it possible for water to freeze in inside house plumbing if the house temperature is 50 deg. or above?
We're going on a winter vacation and I want to turn our house thermostat down to around 55 deg. (in Michigan) However, I've had people tell us we risk having our water pipes freeze at that level of inside air temperature. This doesn't make sense to me, and the people can't explain how the freezing would take place, only that they've heard of this happening.
Immediately before the impact of a golf club with a golf ball, the club is rotating at 1375 deg/s with a radiu?
Immediately before the impact of a golf club with a golf ball, the club is rotating at 1375 deg/s with a radius to the clubhead of 1.6 m. What is the centipetal acceleration of the clubhead?
There is no finite answer to this, since the term Mach (the speed of sound through air or water) changes based on the temperature of the air itself. In 60 deg F air at sea level, Mach 1 is 761mph. In dry air at 68 deg F, mach 1 is 768 mph. ...
our property is all rock and trees and we are about 20 feet above the water. The slope of the embankment ranges from about a 35 deg. to a 70 degree. Would I drill post holes in the rock? or can I just cut some of the rock away to form stairs? or perhaps get cement and stone to shape the rock face? Would it adhere properly?
I already have a college degree but it is pointless. Should I go back to a community college for an associates degree in the medical field?
I have a degree (basically a local university four year degree business management one of those adult education one night a week things) (not University of Phoenix or anything like that but an actual 4 year local university) I am thinking about going to a local community college and getting a deg…
1. Tour the Spanish Chapel. The Cappellone degli spagnuoli, or Spanish Chapel, was originally built as the chapter room of the monastery and was used for morning prayers and readings. The chapel contains frescoes by Andrea Bonaiuti, which depict scen
1. Write down information concerning what qualifies you to teach guitar lessons, as well as information about the guitar lessons. For example, state how long you have been playing the guitar, how long you have been giving lessons, music deg...
I already the know the common sense answer for this. A decrease in temperature difference between the inside of the house and outside of the house means the heat loss is less. Multiply the reduced heat loss by the amount of time the temperature is lower gives a daily (or hourly or whatever) energy savings. I have seen a rule of thumb that for every 1 deg C you drop the thermostat, you get a 2% savings (of course this is over that period of time). Being an electrical engineer (not a mechanical engineer), I want to know what the calculations are for finding this out. Or a link to a site that explains it would be fine. I have already done an internet search, and came up empty after 30 minutes. There are plenty of sites that have built in calculators, but none that I can find that give you the formulas, and the reasoning behind the formulas. It would be nice to be able to input the insulation R value in the mix, as well as the efficiency of the furnace. Thanks!
Aluminized mylar space blankets are large blankets commonly used as part of a camping survival kit. They are waterproof, windproof and, although made of lightweight material, will stay flexible in freezing temperatures as extreme as -60 deg...
Lets say after the positive feedback loop greenhouse effect were complete. What would the avg temps be at the poles be if (for arguments sake) we suddenly orbited a main seq F5 star? How about the equator. Assume still a 24 hr day and 23.5 deg axis tilt? I know some of the ocean would evap but would ALL of it?
sir,i came to know that some peoples are using electrical equipments with capacitors ,that will change single phase supply to three phase supply.as per theory how it is possible,since single phase phase angle is 90 deg. whereas three phase phase angle is 120 deg. please explain with technical details.
We want to leave the not too bad linoleum floor to tile over, but want to get rid of the cove baseboard. How is this doen? Thx Maybe my terminology is off. The linoleum curves at the wall and goes up the wall maybe 3 to 4 inches. Their is a wood piece that helps the linoleum make the 90 deg turn at the floor/wall junction. The baseboard is not the stuff that comes in a roll and glued on.
The national anthem of Italy is called Il Canto Degli Italiani. It was written in 1847 by Goffredo Mameli. Michele Novaro created the music to go along with the song.
1. Decide what angles need to be cut. The vast majority of all corner angles cut on crown molding are 45 degree angles. The reason is simple. A typical corner is 90 degrees, so two complementary angles of crown molding must be cut at 45 deg...
I want to add a layer of foil faced styrofoam to the inside of a double pane picture window. The window has argon gas between the panes. The foil would be against the glass. The heat in the room caused by direct sunlight radiates into the room right through the window shade and will raise the room temperature by 3-4 deg F in 20 minutes. I have heard that this could break/shatter the glass.
