Interpretation Introduction

Interpretation:

To find the heat effect for isothermal process at 300 K

Concept Introduction:

We find the enthalpy of H₂SO₄of pure and 25-wt-% from the H-x diagram of H₂SO₄

Then we find the enthalpy of total solution and then find Q using the below equation,

Q=m3H3−m2H2−m1H1

Where,

Mass of H₂SO₄(100 -wt-%) = m₁

Mass of H₂SO₄_, (25-wt-%) = m₂

Mass of Total Solution = m₃

Enthalpy of H₂SO₄(100-wt-%) = H₁ Enthalpy of H₂SO₄(25-wt-%) = H₂

Enthalpy of % of H₂SO₄ in total solution = H₃

Chemical Engineering Use the psychrometric chart and demonstrate the linear interpolation method to obtain -0.52 KJ/KgDA. This is the enthalpy deviation. The exercise is uploaded below.

Chemical Engineering Use the psychrometric chart. The remaining curves on the psychrometric chart are almost vertical and convex to the left, with labeled values (on Figure 8.4-1) of 0.05, 0.1, 0.2, and so on. (The units of these numbers arekJ/kg DA). Thesecurves are usedto determine theenthalpyof humid air that is not saturated. The procedure is as follows: (a) locate the point on the chart corresponding to air at its specified condition; (b) interpolate to estimate the enthalpy deviation at this point; (c) follow the constant wet-bulb temperature line to the enthalpy scale above the saturation curve, read the value on that scale, and add the enthalpy deviation to it. Also, you will see the exercise on the piece of paper.
