Introduction

Methods

Figure 1 (HT14)

Figure 2 (HT10XC Measurement Service Unit)

In this experiment, heat transfer by natural convection is compared to that of radiation through the large presence of the convection heat transfer coefficient at low surface temperatures and the large presence of the radiation heat transfer coefficient at high surface temperatures through the use of an HT14 apparatus, seen in Figure 1, and a HT10XC Measurement Service Unit, seen in Figure 2. First, ensure the HT14 Combined Convection and Radiation accessory is fully secured in the side of the HT14 cylinder. The T10 thermocouple should be attached from ?

Results & Discussion

Data was compiled into Table 1, below, upon completion of the Heat Transfer Natural Convection lab. The data collected can be seen in Table 1, with the temperatures later being changed into Kelvin.

Table 1 Raw data From Lab

Using equation 3,5, and 7, blah blah blah as seen in Table 2

Table 2 Heat Transfer Rates and Coeffs

Table 3 showcases the bulk of the information calculated in this lab beginning with the qin which comes from the Power supply, and is calculated with Equation 1, as seen with the first trial:

Evaluating the Heat Transfer Coefficients versus the surface temperature, as seen in Figure 3, we can see both are linearly proportional, however hrad has a much great slope, and thusly increases its rate with smaller changes of temperatures than needed for h-conv.

What is MATLAB?A programming platform designed specifically for engineers and scientists to analyze and design systems and products.Initially used for linear algebra operations (hence the name MATrix LABoratory)It?s an interpreted language ?the program can be run (or executed) immediately after being written.

Why is it useful??Used in academia and in industry?Easy to learn and is a great introduction to coding?Applications?Analyzing data and creating figures for research?Machine learning and deep learning?Image filtering?Computational biology?Modeling complex systems?Complimentary with over 500 third party products including:?COMSOL Multiphysics ?Solidworks

Task 1?Create an array of numbers between 1 and 10 with a spacing value of 2.

Task 2?Create an array of numbers between 1 and 10 with a spacing value of 2.?Answer:?a = 1:2:10;?Now create an array ranging from 1 to 10 with five elements.

Task 3?Create an array of numbers between 1 and 10 with a spacing value of 2.?Answer:?a = 1:2:10;?Now create an array ranging from 1 to 10 with five elements?Answer:?b = linspace(1,10,5)?Multiply both arrays with one another.
