Answer:

0.740833917 ton/hr

Explanation:

Given:

Cooling load, 8890.007 Btu/hr = 2.605 kW

Room size = 180 ft^{2}

According to the thumb rule

1 ton of refrigerant = 12000Btu

Hence for 8890.007 Btu/hr,

the mass flow rate of the refrigerant is =8890.007 / 12000

                                                                = 0.740833917 ton per hr

Hence, mass flow rate is 0.740833917 ton/hr

A cylindrical tank is required to contain a gage pressure 670 kPakPa . The tank is to be made of A516 grade 60 steel with a maxi
RSB [31]

Answer:

The minimum thickness t of the wall is 0.00446 mm

Explanation:

Solution

Given that

Pressure =670kPa = 0.670

σ allowable normal stress = 150 MPa

Inner diameter = 2mm

Steel = A516 grade 60

Now,

Since the hoop stress is twice the longitudinal stress, the cylindrical tank is more likely to fail from the hoop stress.

Thus

σ allowable = σₙ = pμ/t

=p (d/2)

150 MPa =0.670MPa * 2/2/t

=0.67/t

t=0.67/150

t =0.00446 mm

Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90)
IrinaVladis [17]

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.
