Chapter 2, Problem 2.8P
Interpretation Introduction

(a)

Interpretation:

The calculations, showing all the units should be carried out.

Concept introduction:

Energy is given by

E=p×t

E = Energy of the system, p = power of system, and t = time.

The international system of unit (SI units):

Day is represented by the symbol d
Week is represented by the symbol wk
Hour is represented by the symbol h
Minutes is represented by the symbol min
Seconds is represented by the symbol s
Microsecond is represented by the symbol µs
Meter is represented by the symbol m
Feet is represented by the symbol ft
Kilometer is represented by the symbol km
Kilogram is represented by the symbol kg
Pound is represented by the symbol lb

Interpretation Introduction

(b)

Interpretation:  To interpret power unit for a plant generate annually.

Concept introduction:

Energy is given by

E=p×t

E = Energy of the system, p = power of system and t = time.

Day is represented by the symbol d
Week is represented by the symbol wk
Hour is represented by the symbol h
Minutes is represented by the symbol min
Seconds is represented by the symbol s
Microsecond is represented by the symbol µs
Meter is represented by the symbol m
Feet is represented by the symbol ft
Kilometer is represented by the symbol km
Kilogram is represented by the symbol kg
Pound is represented by the symbol lb

Interpretation Introduction

(c)

Interpretation:

Why student wrong in saying that plant produces 100MWhr

Concept introduction:

Unit of megawatt is equal to joule per second and power is equal to the ratio of energy and time.

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.
