How do you calculate thermal expansion of a pipe? ΔL = aLo(T2-T1) (Equation 5) If the pipe is installed at an ambient temperature of 70 deg F, and the temperature of the pipe increases to 270 deg F, we can expect about 1.5 in of expansion in the 100 ft unanchored run. How do you […]
Where is the SDS log kept?
Where is the SDS log kept? SDSs must be stored in the work area (not far away or in another building). If electronic copies are used, SDSs must still be available if the area loses electricity or internet access. What does SDS stand for regarding hazard communication? provide Safety Data Sheets Where can you find […]

What is the potential energy and kinetic energy when you release the ball?
What is the potential energy and kinetic energy when you release the ball? When you release the ball, it begins to fall down the track acquiring a speed, v. The ball’s potential energy (PE) is being converted into an equal amount of kinetic energy (KE)! At the bottom of the loop, all of the ball’s […]
How do I see parentheses in stack?
How do I see parentheses in stack? Push an opening parenthesis on top of the stack. In case of a closing bracket, check if the stack is empty. If not, pop in a closing parenthesis if the top of the stack contains the corresponding opening parenthesis. If the parentheses are valid, then the stack will […]
How were simple machines used in ancient times?
How were simple machines used in ancient times? People have used simple machines for thousands of years. Levers, ramps, and pulleys were used in ancient Egypt to build the Great Pyramids. Native Americans who used spears to hunt were using wedges. In the third century BC, the Greek scientist Archimedes invented a way to lift […]

What is a group of interconnected computers called? A network is a group of computers (or a group of smaller networks) that are connected to each other by various means, so that they may communicate with each other. What is a collection of computers and devices connected together called? A network is a collection of […]
What is bright field image in TEM?
What is bright field image in TEM? An image that is produced by the transmitted wave (the wave that undergoes no diffraction) in a diffraction pattern formed on the back focal plane of the objective lens, using the objective aperture. What is used to produce the imaging beam in a TEM? Transmission electron microscopy is […]
Which gear will rotate faster?
Which gear will rotate faster? Increase speed: If you connect two gears together and the first one has more teeth than the second one (generally that means it’s a bigger-sized wheel), the second one has to turn round much faster to keep up. So this arrangement means the second wheel turns faster than the first […]
When at a point liquid phase decomposes into two different solids on cooling then it is known as?
When at a point liquid phase decomposes into two different solids on cooling then it is known as? 4. A eutectic reaction is a three-phase reaction, by which, on cooling, a liquid transforms into two solid phases at the same time. What is the name of the reaction when one solid splits into two solids […]
