Chapter 3, Problem 3.32P
Interpretation Introduction

Interpretation:

The flow rate of air and the percentage of oxygen in the product stream should be calculated.

Concept introduction:

It is given that in order to ignite an air and methane mixture the mole percentage of methane should be between 5% to 15%.

A mixture containing 9 mole% methane should be reduced to lower flammability limit by introducing air at a rate of 700 kg/h.

In addition, Assume that,

Air is consisted of 21 mole% O2 and 79% N2

The average molecular weight of air is 29 g/mol.

Hydrogen (H₂) is considered a clean energy carrier. For its use as a fuel, hydrogen is stored at 5 bar insidea cylindrical tank made of nickel (Ni) with 7 cm inner diameter, 1.2 mm thickness, and the length of L. Thetank is maintained at 358 K. Unfortunately, a small amount of hydrogen diffuses out of the tank, slowlydepleting its contents. You may assume that the hydrogen pressure outside the tank is essentially zero andconvective resistance inside and outside of the cylinder is negligible.• Solubility of H2 in Ni at 358 K = 0.00901 kmol/m3·bar• DH2, Ni at 358 K = 1.2 x 10-12 m2/sCalculate the maximum length of the nickel tank wall to ensure that the hydrogen loss does not exceed0.01 kg per year.
You just took out a cold soda can (at 1 oC) from the refrigerator. Calculate thetemperature of the soda can after the can is placed in a room (at 31 oC, h = 100 W/m2-K) for 60 mins (we all know that soda tastes much better when it is cold!). • k = 0.617 W/m-K, density = 996 kg/m3, Cp = 4178 J/Kg-K• Height = 10 cm & Diameter = 5 cmCalculate the temperature of the soda can surface at the middle point of the heightusing 2-D analysis.
