Sugar solution is being heated to 83 o C in a jacketed pan made from stainless steel, 1.6 mm thick. Heat is supplied by condensing steam at 200 kPa gauge in the jacket. Calculate the rate of heat transfer if the surface heat transfer coefficients for condensing steam and sugar solution are 12000 J/m2-s-oC and 3000 J/m2-s-oC, respectively. Thermal conductivity for the stainless steel is 21 J/m-s-oC and the surface area of the pan is 1.4 m 2 .
The temperature dependence of the vapor pressure is given by the equation:
ΔΗ
RT
Inp = In A –
Where:
p= vapor pressure
T = temperature
A = pre-exponential constant
AHvap = enthalpy of vaporization
In order to solve for the enthalpy of vaporization, AHvap, you must:
Step One
Add the same expression to each side of the equation to leave the term that includes the variable by itself on the right-hand side of the expression:
(Be sure that the answer field changes from light yellow to dark yellow before releasing your answer)
