    Glass Value
AI Thread Summary
The U-value of standard glass varies significantly, with sources citing figures between 1.08 and 5.4. U-value measures a material's insulation effectiveness, being the inverse of R-value. For a single pane window made of ordinary 1/4" glass, a commonly accepted U-value is approximately 1. It's important to verify the specific type of glass and its thickness, as these factors influence the U-value. Accurate information is essential for assessing energy efficiency in building materials.

hey guys just a quick question
Does anyone know the u value of jusy normal glass?
Ive looked everywhere and I've got different answers on source says 5.4 and another says something like 1.08, 5.5 seems pretty high but i think id better find out for sure thanks for any reply's:)

What is a U-value?
 
U value is the inverse of R value which is a measurment of how well a material insulates
 
For a single pane window with plain, ordinary 1/4" glass, I use a u-value of around 1. Here's a table I just googled: http://www.calglassbending.com/secptabl.htm

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
