compute the mass-specific enthalpy change associated with Nz that is undergoing a change in state from 400 k to 800 k

Kitty [74]

Answer:

The correct answer is "430 kJ/kg". A further explanation is given below.

Explanation:

The given values are:

T₁ = 400 k

T₂ = 800 k

The average temperature will be:

= $\frac{T_1+T_2}{2}$

= $\frac{400+800}{2}$

= $600 \ k$

From table,

At 600 k the $C p$ will be = 1.075

Now,

⇒ The specific enthalpy = $Cp(T_2-T_1)$

⇒ $\Delta h=1.075 (800-700)$

⇒ $=430 \ kJ/kg$
