Answer:
V3 = 6.48V
Explanation:
given 12 volts or V = 12V
you need to find the (I) Amps flowing through the total resistors (R) in circuit
R = R1 + R2 + R3
R = 15 + 25 + 47 = 87
the equation to solve for I (Amps) comes from
V = I*R
I = V / R = 12 / 87 = 0.14 Amps
To find the voltage across any resistor R3
V3 = I*R3 = 0.14 *47 = 6.48V
I hope this helps
Answer:
the minimum power input required for this air-conditioning system is 1.20 hp
Explanation:
Given the data in the question;
Temperature inside ( Sink ) T = 70°F = ( 70 + 460 )R = 530 R
temperature outside ( source )T = 100°F = ( 100 + 460 )R = 560 R
= 800 Btu/min
= 100 Btu/min
Now, from the equation of coefficient of performance of refrigerator;
= Desired output / Required input
= / --------- let this be equation 1
= ( ) /
where is the rate heat gained through the wall
is the heat generation from people and lights and appliances.
Now, lets consider the equation coefficient of performance of refrigerator in terms of temperatures;
= / ( - )
we substitute
= 530 / ( 560 - 530 )
= 530 / 30
= 17.667
so we substitute into equation 1;
= / ---------
= ( ) /
17.667 = ( 100 + 800 ) /
17.667 = 900 /
= 900 / 17.667
= 50.94 Btu/min
= ( 50.94 / 42.53 ) hp
= 1.198 hp ≈ 1.20 hp
Therefore, the minimum power input required for this air-conditioning system is 1.20 hp

Answer:
Hence Both technicians A and B are correct that is Technician A says that the system must provide an adequate volume of fuel to the high-pressure fuel injection system. Technician B says that the system must provide fuel at a minimum pressure to the high-pressure fuel injection system are true.
Explanation:
The low-pressure fuel system contains the fuel filters; A fuel level sending unit/tank pick-up; A transfer pump. So from considering both technicians statements both are applicable.
