AI Thread Summary
To determine the thermal transmittance of a floor in contact with the ground, one must calculate the overall heat transfer coefficient using the dimensions provided (20m by 10m) and the materials involved. The first step involves calculating the thermal transmittance of the floor itself, followed by the transmittance coefficient of the wood block surface, which has a thermal conductivity of 0.14 W/mK. Additionally, incorporating an EPS insulation membrane with a thermal conductivity of 0.035 W/mK will further affect the transmittance coefficient. For assistance, it is recommended to search for "thermal transmittance" online for relevant formulas. Engaging directly with knowledgeable individuals can also provide tailored guidance.

Hi I am new here but I am really stuck with this question, I am just looking for any pointers on how to complete this question, thanks in advance for any replys... stevenH

A floor in contact with the ground and having four exposed edges measures 20m by 10m.

i)Determine the thermal transmittance of the floor

ii)If the floor is surfaced with 15mm of wood block having a thermal conductivity of 0.14
W/mK, determine its thermal transmittance coefficient

iii)If the floor has a thermal insulation membrane of EPS having a thermal conductivity of 0.035W/mK in addition to its wood block finish, determine the transmittance coefficient.

i guess your exam is over by now but if you are still "really stuck" on this problem I would suggest Googling "thermal transmittance" and i you'll get some pretty simple formulas to calculate this.

I'm really not trying to be a smart *** here and if you are still stuck PM me and i'll send you a solution;)
 

Thread 'Thread No-Go plug gage allows 3 turns to enter. That's too many!'

After over 25 years of engineering, designing and analyzing bolted joints, I just learned this little fact. According to ASME B1.2, Gages and Gaging for Unified Inch Screw Threads: "The no-go gage should not pass over more than three complete turns when inserted into the internal thread of the product. " 3 turns seems like way to much. I have some really critical nuts that are of standard geometry (5/8"-11 UNC 3B) and have about 4.5 threads when you account for the chamfers on either...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'What type of toilet do I have?'

Thread 'What type of toilet do I have?'

I was enrolled in an online plumbing course at Stratford University. My plumbing textbook lists four types of residential toilets: 1# upflush toilets 2# pressure assisted toilets 3# gravity-fed, rim jet toilets and 4# gravity-fed, siphon-jet toilets. I know my toilet is not an upflush toilet because my toilet is not below the sewage line, and my toilet does not have a grinder and a pump next to it to propel waste upwards. I am about 99% sure that my toilet is not a pressure assisted...
