Consider two Carnot heat engines operating in series. The first engine receives heat from the reservoir at 1400 K and rejects th

Aleksandr-060686 [28]

Answer:

The temperature T= 648.07k

Explanation:

T1=input temperature of the first heat engine =1400k

T=output temperature of the first heat engine and input temperature of the second heat engine= unknown

T3=output temperature of the second heat engine=300k

but carnot efficiency of heat engine = $1 - \frac{Tl}{Th} \\$

where Th =temperature at which the heat enters the engine

Tl is the temperature of the environment

since both engines have the same thermal capacities <em> $n_{th}$ </em> therefore $n_{th} =n_{th1} =n_{th2}\\n_{th }=1-\frac{T1}{T}=1-\frac{T}{T3}\\ \\= 1-\frac{1400}{T}=1-\frac{T}{300}\\$

We have now that

$\frac{-1400}{T}+\frac{T}{300}=0\\$

multiplying through by T

$-1400 + \frac{T^{2} }{300}=0\\$

multiplying through by 300

- $420000+ T^{2} =0\\T^2 =420000\\\sqrt{T2}=\sqrt{420000} \\T=648.07k$

The temperature T= 648.07k

Refrigerant-134a enters a 28-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. The refrigerant gains heat

Alexandra [31]

Answer:

V = 0.30787 m³/s

m = 2.6963 kg/s

v2 = 0.3705 m³/s

v2 = 6.017 m/s

Explanation:

given data

diameter = 28 cm

steadily =200 kPa

temperature = 20°C

velocity = 5 m/s

solution

we know mass flow rate is

m = ρ A v

floe rate V = Av

m = ρ V

flow rate = V = $\frac{m}{\rho}$

V = Av = $\frac{\pi}{4} * d^2 * v1$

V = $\frac{\pi}{4} * 0.28^2 * 5$

V = 0.30787 m³/s

and

mass flow rate of the refrigerant is

m = ρ A v

m = ρ V

m = $\frac{V}{v}$ = $\frac{0.30787}{0.11418}$

m = 2.6963 kg/s

and

velocity and volume flow rate at exit

velocity = mass × v

v2 = 2.6963 × 0.13741 = 0.3705 m³/s

and

v2 = A2×v2

v2 = $\frac{v2}{A2}$

v2 = $\frac{0.3705}{\frac{\pi}{4} * 0.28^2}$

v2 = 6.017 m/s

public class Tester {

public static void main(String[] args) throws IOException {

System.out.println("Enter a Number =======>");

long N ;

while (!in.hasNextLong()) {

System.out.println("That's not a number!");

in.next();

}

N=in.nextLong();

System.out.println("Number Entered is =======>"+N);

System.out.println("Enter a Digit =======>");

int D;

while (!in.hasNextLong()) {

System.out.println("That's not a number!");

in.next();

}

D=in.nextInt();

System.out.println("Digit Entered is =======> "+ D);

long que=N;

int rem;

int count=0;

while(true){

long temp;

temp = (long)que/10;

rem = (int) (que % 10);

System.out.println(temp+" "+ que+" "+rem);

if(rem==D) count++;

que=temp;

if(que==0) break;

}

System.out.println("The number of "+ D+"'s in "+ N + " is "+ count );;

}

Explanation:

Divide the que variable by 10 and assign its result to the temp variable.
Calculate the remainder.
Increment the count if the remainder is equal to the value of D variable and assign the value of que to temp variable.

Select the true statement regarding the PSTN architecture.a. LATA are service providers that control LECsb. a COE is a tandem sw

mrs_skeptik [129]

The fact that an intra LATA call connects subscribers within the same LATA proves the PSTN architecture's correctness.

<h3>What does intra Lata mean?</h3>

Calls placed using the Local Toll Service (also known as IntraLATA Toll, Local Long Distance, or Regional Toll Service) are placed inside of the Local Access and Transport Area.

Calling a phone within the same LATA IntraLATA is the term for local phone service. An intraLATA call is one that travels from one LATA to another, either within the same state or between states.

The customer is charged for intra-LATA calls made to uninteresting neighboring towns. A LATA, which denotes local phone service, is made up of geographical areas.

Local Access and Transport Area, or LATA, is a three digit (5 in Florida) code that designates a particular geographic market where calls are forwarded.
