Answer:
Tc = 424.85 K
Explanation:
Given that,
HEAT FLOW Q is
= 47123.88 w per unit length of rod
volumetric heat rate
= 424.85 K
Answer:
The overflow rate is 4.24×10^-4 m/s.
The detention time is 7069.5 s
Explanation:
Overflow rate is given as volumetric flow rate ÷ area
volumetric flow rate = 0.3 m^3/s
area = πd^2/4 = 3.142×30^2/4 = 706.95 m^2
Overflow rate = 0.3 m^3/s ÷ 706.95 m^2 = 4.24×10^-4 m/s
Detention time = volume ÷ volumetric flow rate
volume = area × depth = 706.95 m^2 × 3 m = 2120.85 m^3
Detention time = 2120.85 m^3 ÷ 0.3 m^3/s = 7069.5 s
Answer:
import java.io.*;
import java.util.Scanner;
public class CountWordsInFile {
public static void main(String[] args) throws IOException {
