Answer:
Given that
D= 4 mm
K = 160 W/m-K
h=h = 220 W/m²-K
ηf = 0.65
We know that
For circular fin
m = 37.08
By solving above equation we get
L= 36.18 mm
The effectiveness for circular fin given as
ε = 23.52

Answer:
Length of pipe meter
Explanation:
Speed of a transverse wave on a string
where F is the tension in string and is the mass per unit length
Thus,
Substituting the given values we get -
Speed of a transverse wave on a string
For third harmonic wave , frequency is equal to
Substituting the given values, we get -
Length of pipe
Substituting the given values we get
for first harmonic wave
Length of pipe meter
Answer:
Explanation:
The spaceship has traveled 3% of the distance to a space station and it has traveled miles.
Let the total distance from the ship's starting point to the space station be x.
This means that:
The total distance to be traveled is .
Therefore, the distance left to travel is:
The answer is 41.25 mph.
The average speed (v) can be expressed as:
v = D/T
where
D is total distance: D = d1 + d2 + d3 + d4
T is total time: T = t1 + t2 + t3 + t4
Now let's calculate distances using the formula: d = v * t:
d1 = v1 * t1 = 20.0 * 0.500 = 10 mi
d2 = v2 * t2 = 40.0 * 1.00 = 40 mi
d3 = v3 * t3 = 30.0 * 0.500 = 15 mi
d4 = v4 * t4 = 50.0 * 2.00 = 100 mi
Thus, the average speed is:
