The upper surface of a 1-m x l-m ASTM B152 copper plate is being cooled by air at 20°C. The air is flowing parallel over the plate surface at a velocity of 0.5 m/s. The maximum use temperature for the ASTM B152 copper plate is 260°C (ASME Code for Process Piping. ASME B31.3-2014, Table A IM). Determine the average convection heat transfer rate from the plate surface that is required to keep the plate surface temperature from going higher than the maximum use temperature

answer:

ok yeah for me again

explanation:

answer:

i need con this question too

explanation:  

an electrode is a metal whose surface serves as the location where oxidation-reduction equilibrium is established between the metal and what is in the solution.

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
