    Measuring the emissivity of a surface

    Hi Techfan, Thanks for your response. I had thought about this and no doubt this is one of the more practical ways to do it - link the coated tiles/bricks to energy saved. I had thought about it this way - build a small chamber with run of the mill firebricks (most common), put a container...

    Measuring the emissivity of a surface

    Hi Fellas, Need your help to solve a practical problem I've been facing. I run a company that makes products for foundries. Recently, we started work on developing a high temperature, high emissivity ceramic coating to paint the inside walls of a furnace. The motive behind the particular...

    Is it Right to Hang a person in the name of Justice ?

    Did I ever say that? I justify the use of death penalty as a punishment for murder, rape & kidnapping & organ trading..Just imagine if you were the victim..tell me now? Dunno about you, but here in India, there are several cases in which an ordinary thief escaped punishment, then he rapes...

    Undergrad Motion in Magnetic Field : Co-Ordinates

    Is there any way we can find the co-ordinates of a charged particle undergoing uniform circular motion in uniform magnetic field, in space ? I tried it using the angular velocity of the particle but it becomes quite complex.. Can anyone help? How about co-ordinates in Helical Motion? Any...

    Undergrad How Does Differentiability Define a Function's Behavior?

    What does the diffrentiability of a given function at some point suggest? What more can we find out about a function if we are given the diffrentiability or non-differentiability at some point? I have some idea on it like the slopes of the tangents to the curve differ, there may be sudden...

    Graduate Mass of Light: How Does It Affect Speed & Gravity?

    Light doesn't have mass...Its mass is 0 otherwise, it wudnt have traveled at c... What happens with black holes is different matter though..It isn't gravity, actually, the black hole wraps space time, and curves space in the shape of a tunnel, so light is actually traveling in straight line...

    Undergrad Why is gravity always attractive?

    The question might sound a lil funny, but it popped up when I was preparing some work on the influence of electrostatic force & gravity... Though electrostatic force can be repulsive or attractive, gravity is always attractive... Then it occurred to me, that its because there are two types...

    Is it Right to Hang a person in the name of Justice ?

    What a joker..Do u think criminals commit crimes in order to get a living? Thats one of the biggest jokes man...So if a criminal murders someone, he's actually doing it for food, if he rapes a woman, he's is actually doing it for food..huh?

    Is Destiny Just an Excuse for Unforeseen Failures and Successes?

    People say that you cannot change your destiny..It is simply inevitable...U just cannot change it.. So, if you are preparing for a very simple exam for 10 years, but destiny has it that you will never clear it, so will you not?? Does this mean, that destiny actually comes into play after...

    Is it Right to Hang a person in the name of Justice ?

    The answer is YES... He deserves to be hanged... Every criminal must be executed if we are to live safely.. Think about this (I dun intend to offend you here), if it was the same person who brutally murdered someone you loved a lot, what wud you say? A man who has taken the life of...

    Oxygen Bond Angle Increase: Reason Behind Increase?

    If we take a look on the following compounds in the Oxygen family, the bond angle increases as we go down the group as : H2O > H2S > H2Se Whats the reason for this increase? Is that : 1. Oxygen is more electronegative than the two, so it holds its lone pairs more tightly than the...

    Crash Test Dummy: Head Impact Parameter & Force Estimation

    "I dun think u can measure that by any measure..." Well...I was thinking whether it wud be possible to actually calculate the force on the head...Vivek, you are right when you say that the motion wud be a bit kind of circular, but it wud be translational too...But I think there are far more...

    Crash Test Dummy: Head Impact Parameter & Force Estimation

    I dun think u can measure that by any measure...Impulse won't do it... Impulse wud solve it only in a case of a particle, I dun think it can be applied in this case...The solution depends a lot on what u want to measure.. I think it requires complex calculations (dun assume it right, coz...
