Answer:
12°F
Explanation:
Calculation for how much subcooling is there in the condenser
Since the CONDENSING TEMPERATURE for 417.4 psig discharge pressure is 120 degrees (120°) which means that the amount of subcooling that is there in the condenser will be calculated using this formula
Amount of Condenser subcooling= Condensing Temperature discharge pressure -Condenser outlet temperature
Let plug in the formula
Amount of Condenser subcooling=120°-108f
Amount of Condenser subcooling=12°F
Therefore the amount of subcooling that is there in the condenser will be 12°F
Answer: 1.58Ω
Explanation:
R1 = 5Ω
R2 = 15Ω
R3 = 3Ω
R4 = 30Ω
The equivalent resistance of the resistor connection (Rtotal) of the four resistors connected in parallel is obtained by adding the reciprocal of each resistance.
i.e 1/Rtotal = (1/R1 + 1/R2 + 1/R3 +1/R4)
1/Rtotal = (1/5Ω + 1/15Ω + 1/3Ω + 1/30Ω)
Make 30Ω the lowest common multiple
1/Rtotal = (6 + 2 + 10 + 1)/30Ω
1/Rtotal = 19/30Ω
To get the value of Rtotal, cross multiply
1 x 30Ω = Rtotal x 19
30Ω = Rtotal x 19
Rtotal = 30Ω/19
Rtotal = 1.58Ω
Thus, the equivalent resistance of this resistor connection is 1.58Ω
Answer:0.4 m
Explanation:
Given
Maximum displacement A=0.49
The sum of kinetic and elastic potential energy is
where k=spring constant
U+K.E.=
when K.E.=U/2
K.E.=kinetic energy
U=Elastic potential Energy
Speed of sound in cold air < Speed of sound in Warm air < Speed of sound in hot molten lead < Speed of sound in water
Explanation:
Step 1:
Speed of sound in water varies from 1450 to 1498 meters per second
Speed of sound in Hot Molten lead is approximately 1210 meters per second
Speed of sound in warm air is approximately 338.89 meters per second
Speed of sound in cold air is approximately 293.33 meters per second
Step 2:
In warm air sound travels faster than that of sound travelling nature in cold air.
∴ Speed of sound in cold air < Speed of sound in Warm air < Speed of sound in hot molten lead < Speed of sound in water
Speed of sound in cold air the slowest while Speed of sound in water is the fastest mean.
Answer:
A problem statement is a concise description of an issue to be addressed or a condition to be improved upon. It identifies the gap between the current (problem) state and desired (goal) state of a process or product.
