Chapter 3, Problem 3.66P
Interpretation Introduction

(a)

Interpretation:

An equation for T (°F) in terms of R should be determined.

Concept introduction:

We have the equation for T as:

T=KRn

Since, the plot of temperature versus dial mark(R) gives a straight line, so the possible relation between T and R may be as per straight line:

lnT=lnK+nlnR

Here, n is described as the slope of the straight line and the y-intercept is explained as K.

Interpretation Introduction

(b)

Interpretation:

The thermostat setting needed to obtain a temperature of 320°F should be determined.

Concept introduction:

We have the equation for T as:

T=KRnT=3.17R1.184

Where, K value is 3.17 and n value is 1.184.

The thermostat setting can better be obtained by getting the value of the dial setting R.

Interpretation Introduction

(c)

Interpretation:

The several possible explanations related to value of R in part (b) should be determined.

Concept introduction:

The thermocouple is a type of thermometer which has an application in industries for measuring extreme temperatures.

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.
