Answer:
The temperature drop is 61.1 °C
The final specific volume of the refrigerant is 1.236 m^3/kg
Explanation:
Initial pressure of refrigerant = 800 kPa = 800/100 = 8 bar
Final pressure of refrigerant = 140 kPa = 140/100 = 1.4 bar
From steam table
At 8 bar, initial saturated temperature is 170.4 °C
At 1.4 bar, final saturated temperature is 109.3 °C
Temperature drop = initial saturated temperature - final saturated temperature = 170.4 - 109.3 = 61.1 °C
Also, from steam table
At 1.4 bar, specific volume is 1.236 m^3/kg
Final specific volume of the refrigerant is 1.236 m^3/kg
Answer:
The code is in the Explanation
Explanation:
#include <iostream>
using namespace std;
int main() {
int xValNew = 0;
int yValNew = 0;
CoordTransform(3, 4, xValNew, yValNew);
cout << "(3, 4) becomes " << "(" << xValNew << ", " << yValNew << ")" << endl;
return 0;}
Answer:
-2/√3 atan ((2t + 1)/√3) + C
Explanation:
∫ (t − 1) / (1 − t³) dt
Factor the difference of cubes:
∫ (t − 1) / ((1 − t)(1 + t + t²)) dt
Divide:
∫ -1 / (1 + t + t²) dt
-∫ 1 / (t² + t + 1) dt
Complete the square:
-∫ 1 / (t² + t + ¼ + ¾) dt
-∫ 4 / (4t² + 4t + 1 + 3) dt
-∫ 4 / ((2t + 1)² + 3) dt
If u = 2t + 1, du = 2 dt:
-∫ 2 / (u² + 3) du
Use an integral table, or use trigonometric substitution:
-2 (1/√3) atan (u/√3) + C
-2/√3 atan (u/√3) + C
Substitute back:
-2/√3 atan ((2t + 1)/√3) + C
Explanation:
Apollo 8 Genesis reading
On Christmas Eve, December 24, 1968, the crew of Apollo 8 read from the Book of Genesis as they orbited the Moon. Astronauts Bill Anders, Jim Lovell, and Frank Borman, the first humans to travel to the Moon, recited verses 1 through 10 of the Genesis creation narrative from the King James Bible.[1] Anders read verses 1–4, Lovell verses 5–8, and Borman read verses 9 and 10.
