A window‐mounted air‐conditioning unit (AC) removes energy by heat transfer from a room, and rejects energy by heat transfer to

Arada [10]

Solution :

Given :

The power of the air‐conditioning (AC) unit is , W = 0.434 kW

The coefficient of performance or the COP of the air‐conditioning (AC) unit is given by = 6.22

Therefore he heat removed is given by , $Q_H = 6.22 \times 0.434$

$Q_H = 2.7 \ kW$

Now if the electricity is valued at 0.10 dollar per kW hour, then the operating cost of the air conditioning unit in 24 hours is given by = 0.10 x 2.7 x 24

= 6.48

Therefore the operating cost = $ 6.48 for 24 hours.

Calculate the diameter of pneumatic cylinder to drive a mechanism. The force exerted by the mechanism is 80 N. The return force

sashaice [31]

Answer:

14.27 mm

Explanation:

Force = 80 Newton

Pressure exerted = 5 bar = 5×10⁵ Pa

Pressure exerted = Force/Area

Area = Force/Pressure

$Area=\frac{80}{500000}\\\Rightarrow Area=0.00016\ m^2$

Area of the cylinder=πd²/4

$\Rightarrow \frac{\pi}{4}d^2=0.00016\\\Rightarrow d^2=\frac{4\times 0.00016}{\pi}\\\Rightarrow d^2=0.0002037\\\Rightarrow d=0.01427\ m$

Hence diameter of cylinder 14.27 mm

2. What is the main job of a cylinder head?

Anna11 [10]

Answer:

Explanation:

The cylinder head sits on the engine and closes off the combustion chamber. The gap that remains between the cylinder head and the engine is completed by the head gasket. Another task of the cylinder head is to ensure the constant lubrication of the cylinder

Write a Person class with a constructor that accepts the following details:

Liono4ka [1.6K]

The person class is an illustration of constructors;

In computer programs, constructors are automatically called when the object of a class is created

<h3>The program in C++</h3>

The class and the constructor program written in C++ programming language is as follows:

int main(){

string fname, lname,dob,idno,mobileno;

cin>>lname; cin>>fname; cin>>dob; cin>>idno; cin>>mobileno;

Person c(fname,lname,dob,idno,mobileno);

if(mobileno.length() == 12){

if(mobileno[3] == '-' && mobileno[7] == '-'){

cout << "Name: " << c.getfname() << " " << c.getlname() << endl

<< "Date of birth: " << c.getdob() << endl

<< "ID number: " << c.getid() << endl

<< "Mobile: " << c.getmobile() << endl

<< "Age: "<< getAge(dob)<<endl;

;

}
