WebDec 17, 2011 · Piping materials exhibit nearly linear expansion and contraction with temperature. The rate of thermal expansion and contraction is characterized by the coefficient of thermal expansion, a, and has units of in/in-°F, or strain per degree Fahrenheit. The change in dimensions of an object is then: ε = a (T 2-T 1) (Equation 4) ε … WebSpecific heat is a property that tells which material gets heated very quickly. So Specific heat is the quantity of heat that we need to change 1 unit degree in unit mass. It is denoted by ‘S’ and the unit is joule/kg Kelvin. Mathematical Expression, (1/m)* (∆Q/∆T) Where. m= Mass. T= Temperature. Q = Energy content.
