The system dependent (passive) recovery process; A) never needs the use of a pump or heat to recover refrigerant. B) must use a pressure relief device to protect the technician and equipment. C) recovers refrigerant in a non-pressurized container. D) can only be performed on a system with an operating compressor.
Answer:
C) recovers refrigerant in a non-pressurized container
The system dependent (passive) recovery process recovers refrigerant in a non-pressurized container. The correct option is C.
A way of recovering refrigerant from a system without using a pump or heat is known as a system-dependent (passive) recovery process.
Instead, it relies on the system's normal pressure and temperature variations to speed up the recovery process.
A non-pressurized container is commonly connected to the system using this technique, and the refrigerant is then passively allowed to flow inside the container.
The system-dependent recovery procedure, according to Option C, recovers refrigerant in a non-pressurized container.
It entails that the refrigerant is gathered in a container without the need of a pump or additional pressure.
Thus, the correct option is C.

A bakery wants to determine how many trays of doughnuts it should prepare each day. Demand is normal with a mean of 15 trays and standard deviation of 5 tray. If the owner wants a service level a at least 95%?
The number of trays that should be prepared if the owner wants a service level of at least 95% is; 7 trays
How to utilize z-score statistics?We are given;
Mean; μ = 15
Standard Deviation; σ = 5
We are told that the distribution of demand score is a bell shaped distribution that is a normal distribution.
Formula for z-score is;
z = (x' - μ)/σ
We want to find the value of x such that the probability is 0.95;
P(X > x) = P(z > (x - 15)/5) = 0.95
⇒ 1 - P(z ≤ (x - 15)/5) = 0.95
Thus;
P(z ≤ (x - 15)/5) = 1 - 0.95
P(z ≤ (x - 15)/5) = 0.05
The value of z from the z-table of 0.05 is -1.645
Thus;
(x - 15)/5 = -1.645
x ≈ 7

Six 20 watt, 12-volt luminaires (lighting fixtures) are supplied from a small, 12-volt transformer that is 60 feet away from the fixtures. the wire used is 14 awg. what is the voltage applied to the fixtures? use k = 11.6.
If the wire used is 14 awg. The voltage applied to the fixtures is: 8.61 volts.
Voltage applied to the fixturesFirst step is to calculate the amperes using this formula
I = P ÷ E
Where:
I =load current (amperes)=?
P =Product of voltage=(6)(20)
E =Electrical circuit's=12
Let plug in the formula
I= (6)(20) ÷ 12
I=120÷12
I= 10 amps
Second step is to calculate the Voltage drop
Using this formula
Vd = [2KIL] ÷ CMA
Where:
Vd= Voltage drop( volts)=?
K=Direct current constant=11.6
I=Load current (amperes)= 10 amps
L =Length in feet=60 feet
CMA=Circular mill area= 4110
Let plug in the formula
Vd= [(2)(11.6)(10)(60)] ÷ 4110
Vd=13,920÷4110
Vd= 3.3869 volts
Third step is to calculate Voltage at fixture
Voltage at fixtures=Electrical circuit's-Voltage drop
Voltage at fixtures=12 - 3.3869
Voltage at fixtures=8.6131 volts
Voltage at fixtures=8.61 volts (Approximately)
Therefore the voltage applied to the fixtures is: 8.61 volts.
