WebOct 7, 2024 · Heat also can impact the electrical resistance of metal. The hotter the metal gets, the more the electrons scatter, causing the metal to be more resistant to an electrical current. Metals heated to certain temperatures also can lose their magnetism. By raising temperatures to between 626 degrees Fahrenheit and 2,012 degrees Fahrenheit ... WebDec 29, 2007 · Hi jrjones. If your simply heating the steel up uniformly then you could use this for an estimate:-. Q= m*Cp* (T2-T1) where m= mass of vessel. Q= heat input in joules. Cp= specific heat of steel. T1 & T2 =intial and final temperatures. Of course you will lose heat while heating up through. convection, radiation and conduction which the above ...

All of these are known.) Then with the help of the formula: ∆ Q = m c v ∆ T = Φ t ( m is mass of metal bar, c v is heat capacity and ∆ T difference ... WebMay 13, 2024 · 1. Fill a heat-safe container with water or oil deep enough to submerge your steel. Use a coffee can or similarly shaped container as your quenching chamber. Pour in water or vegetable oil so it’s 2–3 inches (5.1–7.6 cm) from the rim of the container. Make sure the oil or water is at room temperature.
WebDec 23, 2024 · The formula for specific heat looks like this: c = \frac {Q} {m \Delta T} c = mΔT Q. Q Q is the amount of supplied or subtracted heat (in joules), m m is the mass of the sample, and \Delta T ΔT is the difference between the initial and final temperatures. Heat capacity is measured in J/ (kg·K). WebMar 3, 2011 · Thanks for your helpful recommendations. I attempted to incorporate them in the following analysis and ask for further feedback: Assuming a heat transfer coefficient of 40 W/(m^2-K) for forced indoor air, a characteristic length of 0.075 m, and a thermal conductivity of 16 W/(m-K) for stainless steel, the Boit number is 0.19.
