Answer:
Explanation:
Given:
The two rods could be approximated as a fins of infinite length.
TA = 75 0C θA = (TA - T∞) = 75 - 25 = 50 0C
TB = 55 0C θB = (TB - T∞) = 55 - 25 = 30 0C
Tb = 100 0C θb = (Tb - T∞) = (100 - 25) = 75 0C
KA = 200 W/m · K
T∞ = 25 0C
Solution:
The temperature distribution for the infinite fins are given by
θ/θb=e⁻mx
θA/θb= e-√(hp/A.kA) x1 ....................(1)
θB/θb = e-√(hp/A.kB) x1.......................(2)
Taking natural log on both sides we get,
Ln(θA/θb) = -√(hp/A.kA) x1 ...................(3)
Ln(θB/θb) = -√(hp/A.kB) x1 .....................(4)
Dicving (3) and (4) we get
[ Ln(θA/θb) /Ln(θB/θb)] = √(KB/KA)
[ Ln(50/75) /Ln(30/75)] = √(KB/200)

//Function is written using C++ Programming Language
// Comments are used for explanatory purpose
// The main method is not included
using namespace std;
// Declare arraySum with two arguments. The first represents the array name while the other
// Represents the number of elements
int arraySum(int arr[], int n)
{
int total = 0; // declare and Initialise total to 0
// Iterate through the array to calculate sum
for (int i = 0; i < n; i++) {
total += arr[i];
}
return total;

Answer:
Different types of equipment are required for proper conditioning of air because every air conditional space faces some geometrical and environmental issues or problems. There are some different types of equipment used for conditioning of air that are air system, water system and air-water system. In many cases the air conditioning of the system varies with size of the equipment.
