A square isothermal chip is of width w 5 mm on a side and is mounted in a substrate such that its side and back surfaces are wel

l insulated, while the front surface is exposed to the flow of a coolant at To 15°C. From reliability considerations, the chip temperature must not exceed T 85°C. Coolant T, h Chip If the coolant is air and the corresponding convection 200 W/m2 K, what is the maximum coefficient is h allowable chip power? If the coolant is a dielectric liq- uid for which h 3000 W/m2 K, what is the maxi- mum allowable power?

Answer:

a) 0.35 W

b) 5.25 W

Explanation:

Given that

Width of the chip, W = 5 mm

The environment temperature, T(∞) = 15° C

Surface temperature, T(s) = 85° C

The initial convection heat coefficient, h1 = 200 W/m².K

The final convection heat coefficient, h2 = 3000 W/m².K

Seawater containing 3.50 wt% salt passes through a series of 11 evaporators. Roughly equal quantities of water are vaporized in
statuscvo [17]

Answer: the mass flow rate of concentrated brine out of the process is 46,666.669 kg/hr

Explanation:

F, W and B are the fresh feed, brine and total water obtained

w = 2 x 10^4 L/h

we know that

F = W + B

we substitute

F = 2 x 10^4 + B

F = 20000 + B .................EQUA 1

solute

0.035F = 0.05B

B = 0.035F/0.05

B = 0.7F

now we substitute value of B in equation 1

F = 20000 + 0.7F

0.3F = 20000

F = 20000/0.3

F = 66666.67 kg/hr

B = 0.7F

B = 0.7 * F

B = 0.7 * 66666.67

B = 46,666.669 kg/hr

the mass flow rate of concentrated brine out of the process is 46,666.669 kg/hr

Write an application that reads three integers, adds all three together, computes an average of the three entries, and computes
Natali5045456 [20]

Answer:

//The program prompts user to input three integers and it displays them, adds and gets their average

//begin

public class Test

{

  public static void Main()

  {

     //input intergers

int[] score = new int[3];

      int avg,rem,sum = 0;

     

      for(int i=0;i<3;i++)

      {

      Console.WriteLine("Enter an integer score ");

      score[i] = Convert.ToInt32(Console.ReadLine());

      sum = sum + score[i];

      }

      avg = sum/3;

      rem = sum%3;

     

      Console.WriteLine("The average of "+score[0]+","+score[1]+","+score[2]+" is "+avg +" with a remainder of "+rem);

     

  }
