Answer:
0.285 lbm per cubic foot
Explanation:
Length of tank = 50 inches = 50/12 feet = 4.17 feet
Diameter of tank = 16 inches = 16/12 feet = 1.33 feet
Weight of water = 1.65 lbm
Density of water =?
We know the density of a substance is defined as
ρ = w/v
where ρ is the density in lbm per cubic foot
w is the weight in lbm
v is the volume in cubic feet
Volume of a cylinder =
where d is diameter
l is the length
volume = = 5.79 cubic feet
Hence, the density of water will be
ρ = w/v = 1.65/5.79 = 0.285 lbm per cubic foot
Answer:
Total bandwidth: 8 kHz
Explanation:
Data provided:
Transmitter frequency: 3.9 MHz
Modulation up to: 4 kHz
Solution:
For the upper side frequencies:
Upper side frequencies = 3.9 × + 4 × 10³
Upper side frequencies = 3.904 MHz
For the lower side frequencies:
Lower side frequencies = 3.9 × - 4 × 10³
Lower side frequencies = 3.896 MHz
Consequently, the total bandwidth is computed as:
Total bandwidth = upper side frequencies - lower side frequencies
Total bandwidth = 8 kHz
Response:
The cutting speed is calculated at 365.71 m/min
Clarification:
Given parameters include
diameter D = 250 mm
length L = 625 mm
Feed f = 0.30 mm/rev
cut depth = 2.5 mm
n = 0.25
C = 700
To find
the cutting speed that ensures the tool life coincides with the cutting time for the three parts
The formula for cutting time is given as
Tc =
....................1where D refers to diameter, L refers to length and f refers to feed while V represents speed
Tc =
Tc =
Given the tool life is expressed as
T = 3 × Tc............................2
where T denotes tool life and Tc is the cutting duration
Calculating tool life by substituting values into equation 2 yields
T = 3 ×
This yields V = 365.71
Thus, the cutting speed calculates to 365.71 m/min
Answer:
The duration is 17.43 minutes.
Explanation:
Based on the provided information, the initial diameter is 5 m
the velocity is 3 m/s
and the final diameter is 17 m.
To find the solution, we will use the volume change equation expressed as
ΔV = .............1
where ΔV represents the change in volume, rf is the final radius, and ri is the initial radius.
Calculating ΔV yields
ΔV =
ΔV = 2507 m³.
Thus,
Q = velocity × Area
Q = 3 × π ×(0.5)² = 2.356 m³/s.
Next, the change in time can be expressed as
Δt =
Δt =
Δt = 1046 seconds.
Therefore, the total change in time amounts to 17.43 minutes.
