Chapter 3, Problem 3.65P

Interpretation Introduction

(a)

Interpretation:

The linear equation for V(mV) in terms of T°C and convert it to an equation for T in terms of V should be derived.

Concept introduction:

The voltage and temperature can be related to each other by using following equation:

${\text{V(mV)=aT(}}^{\text{0}}\text{C)+b}$

Here, V is the voltage in milli-volts (mV) and T is the temperature of the system in degree Celsius, whereas a and b are the constants.

Interpretation Introduction

(b)

Interpretation:

The average value of the rate of change of temperature, dT/dt, at the time of measurement period should be determined.

Concept introduction:

The rate of change in temperature with time can be obtained with the help of the equation:

${\text{T}}^{\text{0}}\text{C=18}\text{.10V(mV)+4}\text{.598}$

Interpretation Introduction

(c)

Interpretation:

The principal benefits and disadvantages of thermocouples should be determined.

Concept introduction:

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