Answer:
The work done or the heat transfer for air and hydrogen are 91.71 kj/kg and 1317.89 kj/kg respectively.
Explanation:
Given:
Initial pressure is 7.6 bar.
Initial temperature is 77 °C.
Final pressure is 3.05 bar.
Calculation:
(a)
Take air as an ideal gas with gas constant 0.287 kj/kgK.
Step1
For isothermal process work done and heat transfer is the same because of no change in internal energy.
Work done is calculated as follows:
W = 91.71 kj/kg.
Thus, the work done or the heat transfer for isothermal process is 91.71 kj/kg.
Step2
For isothermal process work done and heat transfer is the same because of no change in internal energy. Take Hydrogen as an ideal gas with gas constant 4.1242 kj/kgK.
Work done is calculated as follows:
W = 1317.89 kj/kg.
Thus, the work done or the heat transfer for isothermal process is 1317.89 kj/kg.
Answer:
claw hammer
Explanation:
A claw hammer is a tool used for driving nails into an object or pulling nails from some other object.
Answer:
#include <iostream>
using namespace std;
int main()
{
int inputNumber ;
cout << "Enter an interstate highway number:";
cin >> inputNumber ;
if(inputNumber<=0 || inputNumber >= 1000)
cout << inputNumber << " is not a valid interstate highway number" << endl ;
else{
if(inputNumber > 99){
cout << "I-"<<inputNumber<< " is auxiliary, ";
int temp = inputNumber % 100 ;
cout <<"serving I-"<<temp<<", ";
if(temp%2==0){
cout << "going east/west." << endl;
}
else{
cout << "going north/south." << endl;
}
}
else{
cout << "I-"<<inputNumber<< " is primary, ";
if(inputNumber%2==0){
cout << "going east/west." << endl;
}
else{
cout << "going north/south." << endl;
}
}
}
return 0;
}
Explanation:
- Check if input number is greater than 99, then display that the input number is auxiliary.
-
Check if remainder of input number/2 is equal to 0, then display that going east/west.
