Chromel specific heat
WebIt is used to measure the temperature of a gas flow with a convective heat transfer coefficient (h) of 500 W/ (m^2 middot K). For lack of better property data, take the junction properties to be the average of those of Chromel (rho = 8730 kg/m^3; c = 450 J/ (kg middot K)) and Alumel (rho = 8600 kg/m^3; c = 526 J/ (kg middot K)). WebIt usually consists of 55% copper and 45% nickel. Its main feature is its low thermal variation of its resistivity, which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients are known, such as manganin (Cu 86 Mn 12 Ni 2 ).
