Answer:
Head loss = 28.03 m
Explanation:
According to Bernoulli's theorem for fluids we have
Applying this between the 2 given points we have
Here is the head loss that occurs
Since the pipe is horizantal we have
Applying contunity equation between the 2 sections we get
Since the cross sectional area of the both the sections is same thus the speed
is also same
Using this information in the above equation of head loss we obtain
Applying values we get
Answer and Explanation:
// code
class Main {
public static void main(String[] args) {
/*
*
*
* your code
*
*/
System.out.println(inDogish("aplderogad"));
System.out.println(inXish("aplderogad", "dog"));
}
// returns true if the word is in dog-ish
// returns false if word is not in dog-ish
public static boolean inDogish(String word) {
// first find d
if (dogishHelper(word, 'd')) {
// first find string after d
String temp = word.substring(word.indexOf("d"));
// find o
if (dogishHelper(temp, 'o')) {
// find string after o
temp = temp.substring(temp.indexOf("o"));
// find g
if (dogishHelper(temp, 'g'))
return true;
}
The output is attached below
}
return false;
}
// necessary to implement inDogish recursively
public static boolean dogishHelper(String word, char letter) {
// end of string
if (word.length() == 0)
return false;
// letter found
if (word.charAt(0) == letter)
return true;
// search in next index
return dogishHelper(word.substring(1), letter);
}
// a generalized version of the inDogish method
public static boolean inXish(String word, String x) {
if (x.length() == 0)
return true;
if (word.length() == 0)
return false;
if (word.charAt(0) == x.charAt(0))
return inXish(word.substring(1), x.substring(1));
return inXish(word.substring(1), x.substring(0));
}
}
