Answer:
Explanation:
Given that
We know that
Rex=ρvx/μ
So
All other quantities are constant only x is a variable in the above equation .so lets take all other quantities as a constant C
We also know that
Nux=hx/K
m is the constant
This is local heat transfer coefficient
The average value of h given as
---------1
The value of local heat transfer coefficient at x=L
-----------2
From 1 and 2 we can say that

Explanation:
Answer:
Taking as a basis of calculation 100 mol of gas leaving the conversion reactor, draw andcompletely label a flowchart of this process. Then calculate the moles of fresh methanol feed,formaldehyde product solution, recycled methanol, and absorber off-gas, the kg of steamgenerated in the waste-heat boiler, and the kg of cooling water fed to the heat exchangerbetween the waste-heat boiler and the absorber. Finally, calculate the heat (kJ) that must beremoved in the distillation column overhead condenser, assuming that methanol enters as asaturated vapor at 1 atm and leaves as a saturated liquid at the same pressure.
