This method works by applying a known heat flux to your sample and measuring its temperature difference. Once the sample reaches a steady-state temperature (temperature across the sample is constant with no cha
Transient Hot Wire Method: A thin wire with a known value is placed in contact with the material in this technique. A constant heat flux is applied to the wire, and the temperature rise is measured. By analyzing the rate of temperature change, thermal conductivity can be determined. Laser F...

What is screw gauge? Give its formula. What is choke coil? A watt meter shows that a motor is drawing 2200 watts. What horsepower is being delivered? What is a 60 mph wind, converted to psi? What do calipers measure? What is an electric kettle's flow diagram?
γLF-interfacial tension at the interface of liquid solder and flux; γLS-the interfacial tension between the liquid solder and the metal. It can be seen from the formulas that in order to improve solder paste wettability (reduce the θ angle), it is necessary to increase γSF or decrease...
Example 1: Using dimensional formula, Q = MaLbTc, find the values of a, b, and c if the given quantity is velocity.Solution: To find: Values for a, b, and cGiven:Quantity = VelocityUsing the dimensional formula,Q = MaLbTcWe know,Velocity = (displacement/time)...
Luminous flux is a measure of the power of visible light produced by a light source or light fitting. It is measured in lumens (lm).
with positive sign if the overall flux is inward, and negative otherwise. The surface integral underneath the calculation of the flux of trajectories can be turned into a volume integral over the divergence of the current through the Gauss’ divergence theorem. If the system is Hamiltonian,\(\pa...
Thanks for your interest. Actually Yes I added a heat flux generation and fixed a convection coefficient of 20 w/m2K. What I wanted to know is if this coefficient is supposed to grow with the velocity inlet or it's gonna be fixed. I am not able to check that because I don't know...
2A). Even if the skin area and diffusional pathlength influence the drug flux through the skin, the driving force defining J is the concentration gradient ΔC. Skin drug delivery systems should be formulated to provide the maximum driving force for passive diffusion across the skin layers, this...
